[PATCH] tests/docker/dockerfiles: Use Fedora 41 for the python container file

[Thomas Huth]

From: Thomas Huth <thuth@redhat.com>

Using "fedora:latest" now fails with Fedora 42:

  Failed to resolve the transaction:
  No match for argument: python3.8

Switch back to Fedora 41 for the time being, to be able to still
test with Python 3.8.

This page details why it is was removed:

  https://fedoraproject.org/wiki/Changes/RetirePython3.8

Based on the explanation there, it seems doubtful that any of our
targetted build platforms have python 3.8. Thus I'd question whether
we should test 3.8 at all.

IOW, rather than pin to fedora:41, it seems better to drop
python3.8 from the dockerfile.

I'm in favor of pinning so that the test is reproducible. A test that
passed on a given git commit should pass again when it is re-run.

It's very inconvenient when tests fail arbitrarily due to unpinned
dependencies. Often the person who has to debug a non-reproducible
test failure is not knowledgeable about the test setup. They shouldn't
have to debug failures unrelated to their patch series.

Yes, we also don't use ":latest" in any of the other tests, so pinning to a 
specific version also sounds like the better idea to me.

Anyway, if we really want to drop Python 3.8 (which we likely should do now 
indeed), we also have to update "configure" and 
docs/about/build-platforms.rst and likely some other spots... John?
