ci: migrate copr publish to reusable action

Replace the in-repo .gitea/scripts/copr-build.sh and per-job
copr-cli configuration with the shared composite action at
https://git.lair.cafe/actions/copr-publish@v1. Behaviour is
identical — submit, watch, dump per-chroot logs — but the logic
now lives in a single place that other projects can consume.

Removes the actions/checkout step from both COPR jobs since the
build script is no longer local to this repo.
