This image is a mere 12MB to pull and it comes with pip, so let's use that
instead of the large Fedora image for jobs where we just run a single script
early in the CI.

The first test pipelines show that the check-commit job finishes in under
30s now (over a minute before). And dnf synching is already 100M to download
+ time, we're a lot faster with this image.

We only have /bin/sh on this image but the only bash job we were running was
the doc build - and that can easily be debashified.
