Pre-commit updates and fixes

[altheaden]

This PR makes a few changes to the pre-commit configuration file and the pre-commit steps in the build CI workflow. I also did some minor cleanup to the build workflow.
Changes:

1. Added an argument to the build workflow python version matrix to not cancel other jobs when a job fails for a specific python version.
2. Added a check that locates the files with changes and runs pre-commit only on those files.
3. Updated pre-commit by running pre-commit autoupdate
4. Cleaned up an unnecessary comment in the build workflow.

@altheaden, these changes look great and are much appreciated!

I'm pretty sure the failed test was just a glitch. But it was a good test that it didn't cancel the other jobs! So what luck that we had a crash :-)
