use pre-commit.ci, remove workflow step running pre-commit. Add pyright to CI workflow

[jakkdl]

Some minor shuffling around of things now that we have pre-commit.ci
A bit ugly to duplicate the typing dependencies, but since we don't pin those it's nbd.

pyright is in pre-commit primarily because I run it locally, but the pre-commit bot will now also bump versions of it, causing it to actually run in the CI action, and everything magically works out.

todo:

• edit the branch protection rules. Will do that just before merging.

ignoring queueing time, pyright action took 18s and pre-commit took 12.1s. Solid improvement over the old check step that took 1m24s as it didn't have access to caching for pre-commit hooks

LGTM, but since transferring the repo I don't have permissions to edit the branch protection rules 😅

[jakkdl]

I do 😁

Removed check requirement, added 3.12, pyright, and pre-commit.
