"update codeowners" action failing

[gsnedders]

See https://github.com/web-platform-tests/wpt/actions/workflows/update_codeowners.yml; it's consistently failing.

Currently:

Presumably the update-codeowners command doesn't actually have a full list of requirements for the venv?

I wonder if we should also make the "update codeowners" workflow run on pull requests that modify .github/workflows/update_codeowners.yml or tools/ci/update_codeowners.py, but only output a diff rather than commit and create a PR, because that would give more confidence that any fix work.
