Move away from node-sass and update documentation related to it

Created by: japalo

Is your proposal related to a problem?

LibSass and Node-Sass is deprecated :https://sass-lang.com/blog/libsass-is-deprecated create-react-app-page is recommending to use it: https://create-react-app.dev/docs/adding-a-sass-stylesheet/

Describe the solution you'd like

I think it should be clear that node-sass is deprecated in the wiki/documentation or it should be updated to reflect packages that aren't.

Describe alternatives you've considered

People i work with suggest migrating to Dart Sass, but i want to make sure that it's fully supported by react-scripts before we migrate to anything.

Additional context

I realize there is an old issue describing how to migrate (https://github.com/facebook/create-react-app/issues/5282) but it doesn't say what is actually preferred as a replacement.
