Description

Wanted to install nightly wheels for a rust integration test when I noticed that the nightly wheels get produced with base version 3.0.0.
This is due to the recently changed release workflow. Now we're creating tags from release branches without a post rebase step, so setuptools_scm fails to find the correct version number on diverged branches.
