Remove retagging from ilab image

[enriquebelarte]

Retag is not needed as we are using static tags now.

Are you sure the image in the additional store ends up labeled correctly?

The retag was instaured because without it "podman images" or equivalent was displaying <none>

[enriquebelarte]

@pastequo If I'm not mistaken the retag was needed because digest tags made the podman images output show tag field as <none> . We're not using digest tags now but static ones that's why my guess is that the code is not needed anymore.
