Subject: [PATCH] Downgrade `sphinx` in doc requirements

I'm seeing the "PyO3 modules may only be initialized once per interpreter
process" errors when creating sphinx documentation. That may be related to more
recent sphinx versions, re: https://github.com/sphinx-doc/sphinx/issues/11662

Downgrade sphinx to an earlier version
