[feature] Add annotations to PR for hook failures

[ddelange]

Annotations from pre-commit errors showing up on the specific lines in the PR diff (e.g. EOF fixer, or flake8 https://github.com/TrueBrain/actions-flake8, pytest https://github.com/utgwkk/pytest-github-actions-annotate-failures) would be very beneficial for developers quickly spotting issues with their code :)

Example annotations:

[asottile]

it runs arbitrary tools which produce arbitrary output -- there's no structured data

you could filter the output to generate the proper ::warning output command but that would need to happen somewhere else

writing to the actual checks-annotations endpoint requires a token as well, which isn't feasible

also development on the github action has ~mostly stopped -- I'd recommend using https://pre-commit.ci instead

additionally I find these check annotations to be incredibly annoying, they don't provide value in my opinion and instead make it much harder to read the code
