With #45689 making it so that index metadata is written after all shards have been snapshotted we can't delete indices that are part of the upcoming snapshot finalization any longer and it is not sufficient to check if all shards of an index have been snapshotted before deciding that it is safe to delete it. This change forbids deleting any index that is in the process of being snapshot to avoid issues during snapshot finalization. Relates #50200 (doesn't fully fix yet because we're not fixing the `partial=true` snapshot case here
