Add AFK Keys counter to /afkshard

when you do /afkshard you see "You currently have 5 AFK Shards.". it would be cool if it also said hoy many keys you have, for example "You currently have 5 AFK Shards and 1 AFK Key". thats not a big change, and makes people not have to guess or have to go to the big sign in the center or the room to see if they have a crate to open
