packages.arasaka.software is published from its own repository; the release only signs the rpm

thepra/packages.arasaka.software now reads this repository's releases and publishes
them with every other joined app, so the daily packages and F-Droid jobs, their
scripts and the repository's F-Droid settings leave this repository. The release
still signs the rpm on its own page with the Arasaka key, as the README promises,
and the F-Droid listing stays in packaging/fdroid/metadata, read at each tag.
