Adjust pre-commit CI config

[TheJulianJES]

Proposed change

This adjusts the title of future pre-commit CI auto-update PRs from "[pre-commit.ci] pre-commit autoupdate" to "Auto-update pre-commit hooks". This matches the current commit message of ZHA's pre-commit auto-update workflow and also aligns closer with how we/HA are naming PRs.
The auto-fix message (for commits on PRs that didn't run pre-commit first) has been changed to "Apply pre-commit auto fixes".

mypy is also dropped from the pre-commit CI action, as we're already doing this in our own CI flow with pre-commit.
