Workaround for python/cpython#100520 (rst syntax error in configparser docstrings), which was fixed in CPython 3.10+.
Docutils raises warnings about the invalid docstrings, and `-W` instructs sphinx to treat this as errors. We can't control or silence these warnings, so we accept them and don't treat them as errors.

See the discussion in gitpython-developers#2060 for details.
