Issue:
[Bug]: Updates to Stylelint config files do not relint file
1. Make changes to the Stylelint config file (e.g. disable a failing rule).
2. Notice that relinting does not occur on the file.

Restarting VS Code relints the file. I believe the problem lies with the watch list being outdated:

The recommended config file names are as follows:

* `stylelint.config.js`
* `stylelint.config.mjs`
* `stylelint.config.cjs`

Alternative filenames include the following:

I split `stylelint.config.{js,cjs,mjs}` and `.stylelintignore` into separate watchers for readability and to avoid nested brackets.
