arch-package.yml ran on push to main and took its version from
`git describe`, so the pacman registry accumulated one package per
merge and not one of them corresponded to a version a user could be
told to install. It builds the tag release.yml cuts instead.
pkgver's literal drops to 0.0.1 with it. That is a downgrade from the
1.x already in the registry, so pacman offers no upgrade and an
existing install has to be removed once; epoch=1 would have avoided
that and is declined in a comment, because an epoch can never be
removed again.
