Please provide support for Symfony 7

[DavidGarciaCat]

Good day,

While testing the new Symfony 7, I noticed the lack of support for that version in both 2.x and 3.x dev branches.

I would like to request support for this new version please, at least for the v3 of this bundle.

Thanks,

I also can contribute with a PR, but I might need some guidance in case there are some peculiarities I should be aware of.

I can see there's an open PR for this (#1165), so closing this issue/request now.
