Proposal

Sass @import is deprecated and will be removed in Sass V3
@use is preferred now.
see https://sass-lang.com/documentation/breaking-changes/import/

migration commands:

$ npm install -g sass-migrator
$ sass-migrator module --migrate-deps your-entrypoint.scss

more informations on migration tool:
https://sass-lang.com/documentation/cli/migrator/

Even if Sass V3 may be far away, it would be nice to upgrade scss files.

Motivation and context

This will avoid numerous warnings and keep boosted usable in future

Hey, thanks for your contribution, however, since we are Bootstrap based, we will probably won't fix it until itself change it. Here is the reference issue FYI: twbs/bootstrap#40962. There are plenty of message about how to avoid the deprecation warning, but the easiest way is probably to fix the Sass Version to 1.77.4 and wait.

Closing the issue since we won't do it on Boosted side, but feel free to reopen if you feel to discuss about this.
