Updated the Debian GitHub Actions workflow to use Debian packaging tooling/dependencies (including dpkg-dev, debhelper, fakeroot, iso-codes, and liblua5.3-dev) so the job is set up for Debian package builds from debian/.

Replaced the previous direct Meson configure/build/test/install steps with a Debian package build step using dpkg-buildpackage -us -uc -b.
Added artifact upload for generated Debian package outputs (*.deb, *.changes, *.buildinfo).
