 call whenever a shard needs to reconnect to the gateway.
 
 ### How it works

 This is because there's a 5 second ratelimit between new sessions. By sending an
 HTTP request to the Gateway Queue, it will ratelimit the requests and "stall"
 them, responding with a friendly message once that shard can reconnect:
 
 ```json
-{"message": "You're free to connect now! :)"}
