[Notifier] Add SentMessage extra info

fixes #20601

I'm not sure any doc should be added: the current sentence regarding the `SentMessage` object is: [The send() method returns a variable of type SentMessage which provides information such as the message ID and the original message contents](https://symfony.com/doc/7.3/notifier.html#sms-channel)
