Galaxy change

Adjust metadata and fix url

[sbesson]

Trying to get my head around the upstream changes which broke the role publication.

Looking at https://forum.ansible.com/t/data-migration-to-the-new-galaxy-ansible-com/1321, ansible/galaxy#3253, https://forum.ansible.com/t/namespace-issue-with-new-galaxy-ansible-com/1325, it feels like the concept of role namespace has been either dropped or maybe more specifically collapsed with github_author.
All OME roles were using the the ome namespace so the impact of this change probably involves updating all GitHub workflows and Galaxy metadata files will need to be updated (again) but it shouldn't cause a full renaming of the roles.

On the keys themselves, it's hard to be authoritative as I cannot find an official reference for the specification. Part of the issue is probably that meta/main.yml is used both for the core Ansible metadata (like role dependencies)) and optional Galaxy metadata. For collections, it looks like the Galaxy metadata is managed into a separate file https://docs.ansible.com/ansible/latest/dev_guide/collections_galaxy_meta.html
The only question is author vs github_author but the changes here look consistent with https://docs.ansible.com/ansible/latest/galaxy/user_guide.html#using-meta-main-yml.

I assume it's going to hard to avoid a trial and error to resolve this one so no immediate objection from my side
