Remove pre-commit update workflow

[TheJulianJES]

We're now using the pre-commit CI app. This automatically creates a PR to update pre-commit hooks every Monday. See this example PR from the quirks repo:

• Auto-update pre-commit hooks zha-device-handlers#3344 (notice how fixes were also auto-applied)

This allows us to remove our own pre-commit update workflow. It can also be removed from the shared workflows repo after this.
