The publish workflow only built a tag whose commit is on main. That keeps
every image tied to reviewed code, but it means production can only get a
fix together with everything that has landed on main since its release.
A tag on a release/* branch is now accepted too. A hotfix branch starts at
an earlier release tag, takes fixes through pull requests into it (so the
code is still reviewed and CI-tested before it is tagged), bumps
brand_version! and is tagged there. The tag must still equal
v<brand_version!>, and the step prints which branch it was found on.
A tag runs the workflow file from its own commit, so a hotfix branch that
starts before this change needs this commit cherry-picked onto it before
its tag is pushed.
