https://github.com/jdillard/sphinx-sitemap/releases/tag/v2.7.0 breaks the CI because it depends on the mgeier/sphinx_get_last_updated_from_git extension. Naturally, that doesn't work with shallow clones which throws warnings.

Options to fix:

• add the git.too_shallow warning to supress_warnings and ignore it
• don't use shallow clones in the CI
• Turn off the option in the sphinx-sitemap extension and don't make use of this new feature. What's the benefit of having this in the sitemap?
• ! Pin all dependencies. I thought I did that already.
