feat: adds stylelint order to the config and demo file

[ryanhagerty]

This is really two commits as additional work was required to be able to commit.

Summary

1. Adds the stylelint-order package and defines our ordering in styleling.config.js
2. Fixes issues with both updated eslint and prettier packages.
   a. eslint now requires a .eslintrc.js file, so this was added to extend the existing index.js config file.
   b. prettier will error out if it cannot find files to lint, so I added the recently introduced --no-error-on-unmatched-pattern flag to the commands.
   c. general linting fixes

Testing

1. Pull down this branch and install the new package.
2. Rename example.property-order.scss.demo to property-order.scss.
3. Run npm run lint and see how we now have warnings when our scss is ordered incorrectly (screenshot below).
4. Throw a party for your family and friends to celebrate scss property ordering. Maybe even rent a bouncy house.

Lets enable auto-fixing by default. From the plugins page Every rule supports autofixing (stylelint --fix).

@callinmullaney I don't think we need to do anything here for that. If you look at the example scripts, there are lint scripts that show issues, and then a lint-fix script that fixes everything. Also, lint staged will auto fix everything anyway. https://github.com/fourkitchens/eslint-config-and-other-formatting/blob/main/package.json

@callinmullaney Brian is correct - the npm command lint-fix will auto fix the property order.
