Remove custom prettier packages to avoid issues with actions failing

[ryanwelcher]

This PR removes the custom prettier fork and related packages and updates the env and scripts packages. This is meant to address the linting actions failing due to previously having to use --force to install due to dependency issues,

@adamziel I discovered some issues in the core data example that I addressed in this PR as well, can you have a quick look to make sure I'm not breaking anything unexpected? The functionality seems to persist as expected just wanted to get a second set of eyes.

It looks like npm is able to correctly resolve aliases now. At least it worked in this case 🎉
