Updating python versions automatically?

[mattip]

It seems 3.12rc1 came out. @mayeut what would it take to get the manylinux bot onto this repo? Is it enough to install it via the install button or do we need to do something to tell it how to update like in PR #43

for some context: this repo builds docker images that can be used to test manylinux c-extension wheels on a debian-based system, to make sure there are no hiccups in the manylinux builds.

I think it would be highly beneficial to be able to update Python versions automatically! Especially if new versions could be added starting from the beta phase.

Truthfully, multi-build has ceded much of its user share to cibuildwheel.
