[Feature] Add Github Actions workflow for pre-commit

[kenibrewer]

With the addition of pre-commit hooks in #264 it would be ideal if these hooks were enforced server side instead of just client side via a Github Workflow.

Because the default pre-commit action runs against all files in the repo, we should format all files in the repo with the appropriate pre-commit hooks prior to adding this workflow.
