[PRQ#51099] Deletion Request for ruby-rack-1

MarsSeed [1] filed a deletion request for ruby-rack-1 [2]: Unneeded legacy gem. Safe to delete, along with its unused, defunct consumers: - ruby-sinatra-1 (PRQ#51098) - ruby-thin-1.6 (PRQ#51095) (These two are the only ones on AUR whose version-constrained dependency declarations would require this gem package).
