Geo: Add package files to status rake tasks

• Add package files to rake geo:status
• Add package files to rake geo:check_replication_verification_status (and ee/spec/lib/gitlab/geo/geo_node_status_check_spec.rb)
• Update https://docs.gitlab.com/ee/development/geo/framework.html#blob-replicator-strategy to ensure new replicables are added to these tasks. Ideally, we'd add package files to the above tasks generically, such that this doc doesn't need to be modified at all. Remember that 3 more blobs are being added in this milestone 13.2, so the duplication will already be painful.

After check_replication_verification_status is added !33834 (merged), this becomes more urgent, like a ~bug for the failover flow.
