Should Mailer::send() return the sent message?

[pdugas]

Symfony version(s) affected: 4.4

Description
Docs indicate Mailer::send() returns the sent message but looking at the code suggests it actually returns nothing. Not sure if this a bug in the code, docs bug, or I'm wrong.

How to reproduce
n/a

Possible Solution
Adjust the docs to reflect the void return of send(). Or change the send() return type to ?SentMessage and return the results of Transport::send() or null if a queue is in use.

Additional context
I suspect the docs are just lagging behind an interface change in Mailer that was necessary to support use of message queues since the sent message isn't available to return.

Your guess is correct,the docs should be fixed.
