Migrate spelling-0.0.21 changes from main

## Summary of the Pull Request

Currently, when the MRU is enabled we lose the keybinding allowing us to 
go forward/backward (aka right/left in LTR) in the tab view.

To fix that, this PR introduces "tabSwitcherMode" optional parameter to 
the prevTab / nextTab commands.
If it is not provided the global setting will be used.


So if you want to go to adjacent tabs, even if MRU is enabled on the
system level you can use:
```
{ "command": { "action": "prevTab", "tabSwitcherMode": "inOrder" }, "keys": "ctrl+f1"}
{ "command": { "action": "nextTab", "tabSwitcherMode": "inOrder" }, "keys": "ctrl+f2"}
```
or even
```
{"command": { "action": "prevTab", "tabSwitcherMode": "disabled" }, "keys": "ctrl+f1"}
{ "command": { "action": "nextTab", "tabSwitcherMode": "disabled" }, "keys": "ctrl+f2"}
```
if you don't want tab switcher to show up

+This document outlines the roadmap towards delivering Windows Terminal 2.0 by Winter 2021.
 
 ## Milestones
 
-The Windows Terminal project is engineered and delivered as a set of 4-week milestones. New features will go into [Windows Terminal Preview](https://aka.ms/terminal-preview) first, then a month after they've been in Preview, those features will move into [Windows Terminal](https://aka.ms/terminal).
