Better Chromium: use Pi-Apps-Coders chromium/widevine mirror

safer than adding the entire archive.raspberrypi.com repo. If the user removed the pin priority they could break their system.

only show libwidevinecdm0 on 22.10+

suggestion from #2528

closes #2528

use force removal of pi-apps-coders-chromium repo

since Better Chromium requires that chromium be installed before running, chromium will never get purged as part of purge_packages since it must have either been marked manually installed or automatically installed by another package
