Migrate spelling-0.0.21 changes from main

We still need to reference MUX
    to get mdmerge happy, but we can't roll that up without rolling up the DLL
    and now we'll get duplicate types in WT.vcxproj. GAH. We'll need to have
    Remoting accept a callback to say "I encountered a commandline, someone,
    deal with it?", then have apphost register for that callback. So the flow
    is monarch->AppHost->AppLogic

-By default the command suggestion will generate a file named based on your commit. That's generally ok as long as you add the file to your commit. Someone can reorganize it later.
-
-:warning: The command is written for posix shells. You can copy the contents of each `perl` command excluding the outer `'` marks and dropping any `'"`/`"'` quotation mark pairs into a file and then run `perl file.pl` from the root of the repository to run the code. Alternatively, you can manually insert the items...
-
-If the listed items are:
-* ... **misspelled**, then please *correct* them instead of using the command.
-* ... *names*, please add them to `.github/actions/spell-check/dictionary/names.txt`.
-* ... APIs, you can add them to a file in `.github/actions/spell-check/dictionary/`.
-* ... just things you're using, please add them to an appropriate file in `.github/actions/spell-check/expect/`.
-* ... tokens you only need in one place and shouldn't *generally be used*, you can add an item in an appropriate file in `.github/actions/spell-check/patterns/`.
-
-See the `README.md` in each directory for more information.
-
-:microscope: You can test your commits **without** *appending* to a PR by creating a new branch with that extra change and pushing it to your fork. The [:check-spelling](https://github.com/marketplace/actions/check-spelling) action will run in response to your **push** -- it doesn't require an open pull request. By using such a branch, you can limit the number of typos your peers see you make. :wink:

-#### :warning: Reviewers
-At present, the action that triggered this message will not show its :x: in this PR unless the branch is within this repository.
-Thus, you **should** make sure that this comment has been addressed before encouraging the merge bot to merge this PR.

The [check-spelling](https://github.com/marketplace/actions/check-spelling) action will run in response to your **push** -- it doesn't require an open pull request. By using such a branch, you can limit the number of typos your peers see you make. :wink:

+# Comment management is handled through a secondary job, for details see:
+# https://github.com/check-spelling/check-spelling/wiki/Feature%3A-Restricted-Permissions
+#
+# `jobs.comment-push` runs when a push is made to a repository and the `jobs.spelling` job needs to make a comment
+#   (in odd cases, it might actually run just to collapse a commment, but that's fairly rare)
+#   it needs `contents: write` in order to add a comment.
+#
+# `jobs.comment-pr` runs when a pull_request is made to a repository and the `jobs.spelling` job needs to make a comment
+#   or collapse a comment (in the case where it had previously made a comment and now no longer needs to show a comment)
+#   it needs `pull-requests: write` in order to manipulate those comments.
+
+# Updating pull request branches is managed via comment handling.
+# For details, see: https://github.com/check-spelling/check-spelling/wiki/Feature:-Update-expect-list
+#
+# These elements work together to make it happen:
+#
+# `on.issue_comment`
+#   This event listens to comments by users asking to update the metadata.
+#
+# `jobs.update`
+#   This job runs in response to an issue_comment and will push a new commit
+#   to update the spelling metadata.
+#
+# `with.experimental_apply_changes_via_bot`
+#   Tells the action to support and generate messages that enable it
+#   to make a commit to update the spelling metadata.
+#
+# `with.ssh_key`
+#   In order to trigger workflows when the commit is made, you can provide a
+#   secret (typically, a write-enabled github deploy key).
+#
+#   For background, see: https://github.com/check-spelling/check-spelling/wiki/Feature:-Update-with-deploy-key

+    Microsoft ResX Schema
+
+    Version 2.0
+
+    The primary goals of this format is to allow a simple XML format
+    that is mostly human readable. The generation and parsing of the
+    various data types are done through the TypeConverter classes
+    associated with the data types.
+
+    Example:
+
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+
+    There are any number of "resheader" rows that contain simple
+    name/value pairs.
+
+    Each data row contains a name, and value. The row also contains a
+    type or mimetype. Type corresponds to a .NET class that support
+    text/value conversion through the TypeConverter architecture.
+    Classes that don't support this are serialized and stored with the
+    mimetype set.
+
+    The mimetype is used for serialized objects, and tells the
+    ResXResourceReader how to depersist the object. This is currently not
+    extensible. For a given mimetype the value must be set accordingly:
+
+    Note - application/x-microsoft.net.object.binary.base64 is the format
+    that the ResXResourceWriter will generate, however the reader can
+    read any of the formats listed below.
+
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
