Remove some unneeded mypy suppressions

These include suppressions that are no longer required because they
worked around mypy bugs that have been fixed, or because they were
not actually effective. It may also include some that are no longer
needed becuase of improvements made to GitPython's type annotations
(or other code) since they were introduced, I am not sure.

This deliberately keeps warn_unused_ignores uncommented in
pyproject.toml, at least for now.
