Autoinject all admin variables

[core23]

Subject

I am targeting this branch, because this feature is BC.

Closes #7242

Changelog

### Changed
- Automatically detect `base_template` and `admin` twig variable

### Deprecated
- Deprecate `CRUDController::renderWithExtraParams` method
- Deprecate `CRUDController::addRenderExtraParams` method
- Deprecate `CRUDController::getBaseTemplate` method

[VincentLanglet]

Deprecated method should be added to the changelog

[VincentLanglet]

A NEXT_MAJOR replace with render() should be added (?)

[core23]

The NEXT_MAJOR comment is pedantic because the annotation should provide enough information

[VincentLanglet]

When we had to resolve all the 4.x NEXT_MAJOR some of them were not obvious, so there is never too much comment.

@psalm-suppress just tell to ignore the deprecation but does not explain how to solve it.

At least

NEXT_MAJOR: Remplace this method by `$this->render`

above renderWithExtraParams definition might be more useful than remove this method.

[jordisala1991]

This method should be depreacted too:

SonataAdminBundle/src/Controller/CRUDController.php

Line 1068 in 4984fc0

protected function getBaseTemplate(): string

Please review again
