Sphinx 5.0.0 was just released, and this build was working yesterday, so I
suspect it's a backwards-incompatible change in Sphinx's behavior.

This failure is blocking changes in `sphinxcontrib-spelling` (see
https://github.com/sphinx-
contrib/spelling/runs/6657712458?check_suite_focus=true for example), so I
have removed that job from the required list for now. When the docs build
here is working again, I'll restore it.

Comment (by dhellmann):

https://github.com/sphinx-contrib/spelling/pull/176 will restore the
disabled job on `sphinxcontrib-spelling`.
