Batch: Improve precommit lint/format checking

[JamesMGreene]

Our current git precommit hook only checks if our code linting and/or formatting has errors, but does not actually fix such errors when possible.

This is something that is definitely achievable.

Draft PR from the old backend repo: OpenSourceFellows/amplify-back-end#145

⚠️ ☝🏻 As you can read in that PR, there were some issues I ran into that prevented me from moving ahead with it at the itme, even though they may not truly be blockers. 🤷🏻‍♂️

Moved this to this issue #89

[JamesMGreene]

The concept here is fairly different from that of #89. This one is more to do with the infrastructure/tooling vs. the specific lint/formatting rules in use. 🤷🏻‍♂️

Going to reopen. 🙏🏻

@JamesMGreene is OpenSourceFellows/amplify-back-end#145 in a private or archived repo?

[JamesMGreene]

@joshjohanning Ah, good call. It was an archived repo that I went ahead and made private to avoid confusion but I can make it public again since we're referencing it. 😅 👍🏻

Should be available now if you check again! Thanks for pointing that out. 🙇🏻‍♂️
