CI: keep quartz-pages.yml (it deploys gamecult.org on GitHub Pages)

The shared workflow is called by gamecult-site's deploy-quartz.yml and
publishes the live gamecult.org through GitHub Pages. It builds no
container image, and it needs GitHub-hosted runners, so it stays on
ubuntu-latest; the forge has no Pages deploy.
