Summary
This upgrades our version of dart-sass to 1.45.0 and includes cleanup necessary to prevent stylelint from crashing during build.
This PR completes 2 of 3 tasks in #1380 (closed). We don't need to fully migrate in order to upgrade dart-sass (yet).
Important changes
-
mappy-breakpointsis now a local dependency incss/imports. It's functionally identical to its NPM counterpart, but it makes use of new SASS syntax is so that the project can build. If the published NPM package receives appropriate updates, we can go back to using it, but I don't expect that to happen soon. - many of our other
.scssfiles have been passed throughsass-migratorso that they utilize new SASS syntax as well.
