Enable pre-commit.ci autofixes

[antonymilne]

Description

This PR enables automatic linting fixes using pre-commit CI. Please watch the team learning session for a full introduction.

I have left autofix_prs enabled for now because I think it's the best option to try out. If we find it a nuisance then we can switch to a different workflow where you need to manually comment pre-commit.ci autofix in order to trigger the linting fix.

What this means is that pre-commit CI will automatically make linting fix commits on your branch, and if you try to push on top of that you will get a failure from git "Updates were rejected because the remote contains work that you do not have locally". If you use PyCharm then a window will pop up:

The recommended strategy is "Rebase". Tick "Remember ..." if In future you don't want to be prompted again (also recommended).

If the window didn't pop up or you clicked the wrong button or something then you can also specify this in your PyCharm settings:

If you do git from command line then I recommend setting

git config pull.rebase true
git config rebase.autoStash true

You could also set an alias for git pp to do "pull and then push":

git config alias.pp '!git pull && git push'

Also FYI @AnnMarieW (I still couldn't add you as reviewer here so will check the settings again). The intention of this is to make the contribution process smoother so that you don't even need to run hatch run lint - instead the fixes should be applied automatically in your PR.
