chore(ruff[lint]): Allow exec in the Sphinx config

why: `docs/conf.py` collects the project's title, copyright, and URLs by
exec'ing the package's `__about__.py` into a dict, because
`g/__init__.py` re-exports only `__version__`. The input is a tracked
file in this repository, not user data, so the flake8-bandit warning has
nothing to warn about here.

what:
- Per-file-ignore S102 for `docs/conf.py`
