[Messenger] Update the list of stamp

This PR updates the list of stamps. In the current docs it looks like the list of stamps was complete. I think we should just highlight important ones that users will come in contact with. Advanced users will find the rest of the stamps anyways.

I sorted the list alphabetically. I added DelayStamp and DispatchAfterCurrentBusStamp

 Instead of dealing directly with the messages in the middleware you receive the envelope.
 Hence you can inspect the envelope content and its stamps, or add any::
