[cinder] transition train to end-of-life

As discussed at the cinder weekly meeting on 2023-05-31 [0], the
cinder project wishes to declare the stable/train branch of all
branched deliverables EOL and requests that the release team delete
the branch.

The stable/train branch of cinderlib was previously made EOL and
deleted by change I25d78267ab4a.
