Need install dev-requirements in test jobs (#955)

`distutils` is needed by the bazel test jobs, but it was removed in
Python 3.12. This is causing those test jobs to fail in CI.

Adding `pip install -r dev-requirements.txt` to those jobs will install
`setuptools`, which will in turn satisfy that requirement.
