pre-commit-config: do not reformat schemas

[pjonsson]

Reformatting will give spurious differences
after running the update.sh script.

I'm not sure how to test this without doing an actual update and see what the precommit bot does, so I might have missed something. Considering #546, I don't want to change things too much.

Sorry if I'm explaining things you already know...

Pre-commit should be installed locally, and then pre-commit install should be run for within each repo using it.

After doing that, it's possible to do a "test run" using pre-commit run --all-files, which is AFAIK what the pre-commit service does.

I know very little about best practices for interpreted languages, thank you for explaining!
