DEV: Move to Sass compilation to dart-sass (#19910)
This PR is a major change to Sass compilation in Discourse.

The new version of sass-ruby moves to dart-sass putting we back on the supported version of Sass. It does so while keeping compatibility with the existing method signatures, so minimal change is needed in Discourse for this change.

This moves us

From:
  - sassc 2.0.1 (Feb 2019)
  - libsass 3.5.2 (May 2018)

To:
  - dart-sass 1.58
