fix: address code review — publish.yml permissions, test docstrings

- Add contents: read permission to publish.yml (required for actions/checkout)
  when any permission is explicitly set, unlisted permissions default to none
- Add timeout-minutes: 15 to publish.yml for consistency with ci.yml
- Add docstrings to 3 pyproject metadata test functions for consistency
  with the rest of the 2000+ line test file
