SymPy is now in the GitHub actions beta. If anyone wants to play
around with it, go ahead. You should see the new "actions" tab at the
top of the page (it might require push access to show up, I'm not
sure).
Let me know if you want to play with it but need more access than what you have.
One idea for something we could do with it would be to build a bot
that builds any new or modified docstring from a PR in Sphinx and
posts a screenshot of it
