Upgrade all patch and minor upgradeable packages, also uses `only`
in ember-cli-build to reduce the included helpers from certain helper
packages.
Make some major version upgrades for some dev tools
- husky
- lint-staged
- ember-cli-yadda
- ember-cli-sass (also moved from node-sass to dart-sass)
Minor tweak: spotted css file (instead of scss file), rename
The move to `dart-sass`:
dart-sass has been the primary implementation of sass for ~6 months and
will receive updates earlier than libsass (ruby-sass itself is now deprecated)
Other benefits include not having to recompile (via `npm rebuild` or similar)
when switching platforms and an 'almost' javascript based solution.
This update also alters some media queries that, whilst wouldn't compile
anymore with either an updated libsass or dart-sass, where probably a
little over complicated anyway, I've therefore made them similar to
other breakpoints that made sense.
