CI fails for KGeoTag

[Tobias Leupold]

Hi all :-)

Currently, CI fails for KGeoTag on the systems that are added automatically 
(not on the ones added manually), cf.

    https://invent.kde.org/graphics/kgeotag/-/jobs/1842186
    https://invent.kde.org/graphics/kgeotag/-/jobs/1842188

It's something about a missing dependency:

    raise Exception(f"Package {identifier} was not found in branch {branch}")
    ...
    raise Exception("Unable to locate requested dependency in the registry: {}
    (branch: {})".format( identifier, branch ))
    ...
    Exception: Package marble was not found in branch release/23.08

I didn't change anything in the CI config. Apparently, I missed some change, 
didn't update a config file or such?

Could somebody give me a hand about this? Thanks a lot in advance!

Cheers, Tobias
