Upgrade to Sonata 4

[jordisala1991]

Subject

I am targeting this branch, because this includes a lot of BC breaks.

Part of #1416 #1417

Changelog

### Added
- Add support for Sonata ^4.

I imagined that you could fix this faster then me 😄

But for your pipeline pass you need to use 4.x as 4.14.0 or create a release in sonata admin

[eerison]

because of this PR: sonata-project/SonataAdminBundle#7867

[jordisala1991]

I know, but I wanted to start the Pr to see how it looked.

[SonataCI]

Could you please rebase your PR and fix merge conflicts?

We will need you @eerison to both try the 3.x branch (in order to release all the deprecation) and to try this branch (with Sonata 4) to confirm that everything work as expected.

For the 4.x branch, it can still be done later or when the alpha will be release. But the 3.x branch should be tested because it will be a pretty huge release.

Ok tomorrow on the morning I'll test 3.x release and I will confirm here :)
