I should have done this before publishing the build, but it's too late
now. Instead, I'll update it here and continue forward with gbp-dch to
help generate more correct changelogs.
I'm switching to use nested tags for the packaging branches. I want to
have a deb/bookworm and a deb/experimental branch. The gbp-pq tool
already seems to do this, so I'll follow it's lead.
