Autoformatting with github actions

[GreatGreenStar]

This will allow manual build validation and code format checks, to use as desired.

When code is pushed or a pull request is made, said code will now be checked for if formatted properly. If code is NOT formatted properly, it will trigger another action which DOES format it properly and commits the fix to do so.

Note that after code is formatted by spotless, it will for a moment hide the checks because it cannot run against itself per https://github.com/marketplace/actions/add-commit#the-commit-from-the-action-is-not-triggering-ci
Fixing would add needless complexity, as you can simply look at the last human commit. Further, it should still block/allow based off the last checks against a human, so blocking commits that don't build should still work in full.

For most of the times I quickly made multiple commits in under a minute I let copilot generate the commit message so a lot of the "in-a-row" commits are... questionable. that said, I assert that given my above comment about checks appearing to partially vanish under certain conditions and how they don't in actuality, this works.
