Add tests for language pack extensions

fix: spelling mistake correction

- Correct spelling mistake in `commonEditorConfig.ts` file
  - Change word from `mulitiplier` to `multiplier`

Note:
- Potentially affects "Get Started - User and Workspace Settings"
  https://code.visualstudio.com/docs/getstarted/settings
  page's listing of the default editor config parameters,
  as those still include the (probably) generated mispelling.

Use array of string for applicable builtin settings
