Add CentOS Stream with EPEL Python 3.13

[frenzymadness]

Issue to solve in minimal container:

(microdnf:24): librepo-WARNING **: 13:00:03.044: LRO_METALINKURL processing failed: Status code: 404 for https://mirrors.fedoraproject.org/metalink?repo=epel${releasever_minor:+-z}-10&arch=x86_64 (IP: 38.145.32.20)

Updating the base image fixed the problem but now, installing epel-release installs 57 packages 🤔

It seems it works, and I'm quite happy with how easy it was to implement it. @phracek could you please check it? Are there any preps required on quay.io side? I see the tests run for 3.13 on C10S here, but I don't see them for the new minimal container. Do you know why?

I also noticed there are no changes to README. But maybe it will get updated once there are images to link to?
