Hi, sorry for not coming up with a straight pull request containing a solution. I'm just evaluating the framework, and while reading the examples I just noticed that [an example responds with the same result regardless ack event had been sent successfully or not](https://github.com/marblejs/docs/blob/f63768d69efebef322627065e4b1b04fa9c2c9fe/messaging/microservices/rabbitmq.md?plain=1#LL103C1-L103C44). Am I wrong?
