build: replaces node-sass with sass

[mcataford]

Description

node-sass is now deprecated and the suggested replacement is dart-sass. This substitutes one for the other. Major pro for this: node-sass did some heavy node-gyp building whereas this doesn't, making building-from-scratch way faster.

QA: diff'ed CSS output before and after the change, they are functionally the same. sass seems to insert a handful of extra newlines, but otherwise, same stylesheet. :+1:
