@hugovk I appreciate it but this was about the dark theme, no?

Yes, we're pinning to the last versionbefore the dark theme was added.

This the minimal fix, because the dark theme requires Sphinx 3 for proper syntax highlighting, and the 3.8/3.9 docs use Sphinx 2.4.4.

We can look into bumping Sphinx to 3+, but it will likely also require bumping other dependencies, and for security branches I felt it would be easier/safer to pin to an older python-docs-theme.

Ah, got it. Right. Okay then, let's go.
