so I got the idea to remove this since logs were getting spammed with:

WARNING  Another version of 'alfresco.acs' 1.0.0 was found installed in /home/runner/.local/share/virtualenvs/alfresco-ansible-deployment-cebUtTOi/lib/python3.11/dist-packages/ansible_collections, only the first one will be used, 1.0.0 (/home/runner/.ansible/collections/ansible_collections).

which was getting worse when molecule was triggering a retry like in https://github.com/Alfresco/alfresco-ansible-deployment/actions/runs/13240172999/job/36956143762#step:3:3708

once I dropped this, then all the single role galaxy metadata was starting to trigger validation issues due to missing namespace, so I decided to revamp all of them which was anyway required.

at this point I am not sure if the root galaxy.yml was just inhibiting all the role galaxy.yml and I think it's a feature (because in that case roles are part of the collection)

I am not sure what to do, but maybe given we are not currently publishing anything we can leave it as it is now.
