ci: Try falling back to stable branch before HEAD

Browse Source 
For non-MR pipelines, we check for a matching branch or tag name
in mutter. As we use the same naming policy for stable branches
and branch at about the same time, this works generally fine for
branches.

However for tags, it is less unlikely that there is no matching
tag in mutter, in particularly late in a stable cycle when most
changes are translation updates (which are much rare in mutter
than gnome-shell).

Before falling back to main (which is doomed to fail in that case),
try to guess the correct stable branch based on the tag name.
