We had Prettier pinned because of https://github.com/prettier/prettier/issues/5529. Since that bug is fixed, unpinning.
Prettier now supports YAML, so this applies Prettier to all .yml except for translations, which should not be edited directly anyway.
Run `prettier --write "app/assets/stylesheets/**/*.scss" "plugins/**/*.scss"` after making sure you installed it with `yarn`
It's recommended to configure your editor to run prettier on file save.
