Package: httpd: version:
Expected
    ["2.4.57-11.el9_4"]
to contain elements matching
    ["2.4.57-8.el9"]
the missing elements were
    ["2.4.57-8.el9"]

I'm guessing the image checksum logic isn't working and the images are getting rebuilt, so package versions are drifting on the tests.

The update of httpd is part of #961

The image checksum logic would work. But this need to upload the image to https://hub.docker.com/u/aelsabbahy and create a checksum file.

The alternative with the ghcr is part of #901
