5680 Sass linter

[rfultz]

Summary

• Resolves Sass Upgrade - Stylelint #5680

Adding Stylelint to our build process

Required reviewers

A few who can check through rules and various types of pages and their appearance.

Impacted areas of the application

Technically the entire site. Realistically, very little will be affected but I'd like to check:

• accordions
• callouts
• cards
• data-landing-callouts
• components/documents (box-shadow)
• components/examples (box-shadow)
• components/form-styles (hover.is-disabled, [disabled])
• mega-menu (.mega box-shadow)
• mixins/u-visually-hidden
• pres-finance-map (currency column font, flex, stroke)
• org chart

How to test

• Pull the branch
• npm i
• npm run build (or just npm run build-sass) (should be no errors, though there may be deprecation stylelint warnings)
• If your IDE support it (VS Code should)
  • Open a scss file and make some errors
  • Those errors should be indicated
• Auto fixing formatting errors
  • Open a scss file and make some errors that can be easily fixed (like extra spaces at the end of a line)
  • Save the file
  • npm run format-sass-fix
  • Check that the errors have been fixed
• Pages
  • Make sure the components above are 'normal' across widths (will add links or better descriptions)
