Is there a RTD version of this we can look at?

[tecoholic]

@pdpinch The previous CI run failed due to some issue with the RTD build. It is available here now.

On a related note, do you happen to know the right person I should ping for reviewing and merging this?

[feanil]

@tecoholic it should probably be reviewed and merged by the same person who reviews and merges openedx/edx-platform#33310, if they don't have merge rights here, they can approve it and tag me and I can merge it for y'all.
