This PR adds a new Mailer bridge for [Resend](https://resend.com/).
In addition, it handles the webhooks sent by Resend for various events (sent, delivered, delivery_delayed, bounced, clicked, opened, complained).

The bridge and webhooks has been tested in a real 7.1 project (I can provide the reproducer if anyone want to test it).

Thanks to `@zenorocha` and all the Resend team for this tool!

NB: Docs PR will land later this week
