rulez: drop nano from the v2023_repositories list

By default gitlab-rulez defines the default branch based on the value of current_release_branch which is currently "apertis/v2025pre".

But some packages have been dropped from Apertis in previous releases, that means they don't have the default branch. Thus we need to teach gitlab-rulez what is the latest branch to use as default branch.

nano was in the v2023_repositories list since its default branch was apertis/v2023 because it got removed after. Now that it has been re-added in apertis/v2025pre, gitlab-rulez can rely on the current_release_branch to define its default branch.
