Raise warning on invalid color scheme in commands

[mpela81]

Show a validation warning when someone sets a setColorScheme action
with an invalid scheme

In the setting validation phase, scan all commands for all the "set
color scheme" actions, and check each of them has a valid scheme. If any
of them has an invalid scheme name, raise a warning. Do not check
iterable commands that will be expanded to valid color schemes.

Validation Steps Performed

• Added tests to LocalTests_SettingsModel
• Manual tests, add commands to settings.json with invalid color scheme
  and check the warning pops up. Try simple and nested commands.

Closes #7221

✏️ Contributor please read this

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.

⚠️ 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.

🔬 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 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. 😉

This is great, super straight-forward, and has tests. Sorry it took us so long to get to this!

[DHowett]

Very straightforward. I also apologize for not reviewing it quickly.

[DHowett]

We will probably want a stronger data model in the future such that these are impossible/unnecessary. 😄
