[Notifier] Add FreeMobile SMS entry

Hi,

I was reading this [blog post](https://symfony.com/blog/new-in-symfony-5-1-new-and-improved-integrations#notifier-component)
and remind I have not yet added it to the doc [this feature](symfony/symfony#35690)

Just a question as I am not sure where and how to document the fact that this sms notifier is a bit special, is it ok like this in the `versionadded code block`?

or maybe it is better in a note afterward?

Thank you
