Nobody forbids this... ;-)

And I was wrong, our current GitHub workflow _is_ triggered by tags. See
e.g. https://github.com/git-for-windows/git/actions/runs/83103626 which
was triggered by v2.26.2.windows.1.

However, you also see that it failed due to the reason I described in the
commit message.

I guess that we should either go with this patch (which would trigger full
runs also on tags), or we could alternatively trigger only on branch
pushes (and not tag pushes)?

Ciao,
