The ruby/setup-ruby action needs a version of Ruby specified to work. Previously it was reading the .ruby-version file, however we removed that in commit 2aa58c. We could restore that file, but because ruby-install doesn't support loose version specifiers, we'd have to keep it maintained. Instead we just tell the action to install the latest version of Ruby 3.
This PR fixes the publish workflow.
