licensing: add SPDX AGPL-3.0-or-later headers to .github/ files authored by Enrico Weigelt

All 47 files in .github/ (actions, arch, docker, scripts, workflows)
that were originally authored by Enrico Weigelt and don't end up in
the final X server binary now carry SPDX-License-Identifier headers.

File .github/scripts/ubuntu/run-pyxtest-valgrind.sh already had the
AGPL-3.0-or-later header — left as-is.
