fix: use upstream instead of shared Prettier configuration for this repo

Use Prettier configuration from upstream repository (https://github.com/kentcdodds/kcd-scripts) instead of the shared configuration distributed with this package from `src/config/prettierrc.js` in order to maintain the ability to merge the upstream repo.
