OK, I have turned pre-commit on for the main repo (it was already on for pytest-mpl and ipympl). I am not super stoked that it has the ability to push to the main repo, but it is not the only application with similar access.

@tacaswell turned on pre-commit.ci for PR #22777

following discussions in PR #22809, PR #22777, and on Gitter.

There was not a clear consensus if the dev team was comfortable with another service that has push permissions like those shown in matthewfeickert#9 being connected to the matplotlib/matplotlib repo and if the examples shown in matthewfeickert#12 provided information that was acceptable.

Given #22777 (comment)

I'm in favor of getting this running on CI in any way that marks with a red-x, merging this, and then iterating on how best to notify at what needs to be changed.

pre-commit.ci was turned on, but the dev team should decide if they are happy with it or not. If they are happy with it, I am willing to help answer any questions they have in the future on it and make demo PRs on my forks of any situations they might be concerned with. If they are not happy, I am willing to help implement a solution that is acceptable to them.
