Add GitHub Action for lint

[SpencerKaiser]

When making a pull request, listing should be considered and branch protection should be enabled to require a pass from the lint action before a PR can be merged.

Note: there are quite a few files in the repo that need to be updated with yarn lint:fix before this can be turned on without creating new failures
