MAINT: switch to maintained prettier fork

[bsipocz]

trivial little PR, I was batch cleaning the repos I have locally.

@bsipocz why would we switch away from the official pre-commit mirror?

That repo is archived: https://github.com/pre-commit/mirrors-prettier and the latest alpha release always causing problems with the pre-commit auto updates.

There are a couple of forks now, Jarrod has started switching many of the repos to this one, but now I also see a https://github.com/pycontribs/mirrors-prettier.

(I opened these switch PRs to the repos I have a local copy for as I noticed that there new forks when I was reviewing the automated PRs today.)

The link you mention is maintained by a lead Ansible developer, so that should be reliable. I just don't want us to point somewhere where we don't know the developer or their credentials.
