feat: Build with node 16 + get off of node-sass

[msnyder-msft]

Summary of changes 🔍

Node-sass is deprecated, and is what was pinning us to Node 14 (which is also deprecated) so we will get off of node-sass using Dart-Sass which will free us up to get to node 16 which is currently in LTS. Dart-sass exposes the same JS API so it's a drop-in replacement.

Migrated our node-sass command line to dart-sass command line - docs

Note: NPM package install started failing with a conflicting peer dependency if we go to node 18, so postponing that migration for another time.

Testing 🧪

• I ran the build locally and in the pipelines to make sure those worked.
• I ran storybook and it looks like all the styling stuff is still looking good.

When we try to get to node 18 we get stuck with this failure and it's been a rabbit hole.
