Fixed a few developer gotchas

- Update the run_tests.py script to ensure that the correct version of the
  'ksconf' package is used for testing rather than any-old version that may
  have been previously installed.  Before this should have been the default
  behavior, but it could have failed if running this script from a different
  working directory.
- Fix long-standing issue with local pre-commit hooks where make_cli_docs and
  unittest were always run, even if there were no changes to python files.
  Caused by a typo.
- Fix entrypoint fallback missing functionality (I think ONLY used by a
  unittest, but for the entire 2 mins it took to implement, it's done.)
- Bump pre-commit repo to latest version of the hooks.
