chore: silence import and global builtin deprecation warnings in sass build

[jmuzina]

Done

Silences numerous deprecation warnings from being thrown into the console output on building Vanilla. These are currently slowing the build down and are not planned to be fixed currently as we work on the new architecture.

Silenced the import and global-builtin deprecations per sass documentation

QA

• See that sass still builds and the console output no longer has any deprecation warnings

Check if PR is ready for release

If this PR contains Vanilla SCSS or macro code changes, it should contain the following changes to make sure it's ready for the release:

• PR should have one of the following labels to automatically categorise it in release notes:
  • Feature 🎁, Breaking Change 💣, Bug 🐛, Documentation 📝, Maintenance 🔨.
• Vanilla version in package.json should be updated relative to the most recent release, following semver convention
  • if existing APIs (CSS classes & macro APIs) are not changed it can be a bugfix release (x.x.X)
  • if existing APIs (CSS classes & macro APIs) are changed/added/removed it should be a minor version (x.X.0)
  • see the wiki for more details
• Any changes to component class names (new patterns, variants, removed or added features) or macros should be listed on the what's new page.
