Original Pull Request: https://github.com/microsoft/terminal/pull/7241

State: closed
Merged: Yes

This pull request completes (and somewhat rewrites) the JsonUtils error
handling arc. Deserialization errors, no longer represented by trees of
exceptions that must be rethrown and caught, are now transformed at
catch time into a message explaining what we expected and where we
expected it.

Instead of exception trees, a deserialization failure will result in a
single type of exception with the originating JSON object from which we
can determine the contents and location of the failure.

Because most of the error message actually comes from the JSON schema
or the actual supported types, and the other jsoncpp errors are not
localized I've made the decision to not localize these messages.
