Add a release-package job (gated on v* tags, after build-and-test) that
builds the Release configuration for x86_64, ad-hoc signs the app bundle so
UNUserNotificationCenter works in the distributed build, archives
MacMonitor.app via ditto, uploads it as a workflow artifact, and creates a
Gitea release with the zip attached via the API token.
