feat: Controller now use trait for better use in EasyAdmin

[DylanKas]

This pull request modify the EasyAdminController to use a trait and make it easier to use other extension with EasyAdmin. (Example: WandiParis/EasyAdminPlusBundle)

It has been tested on a local projet that use both Wandi and AlterPHP extensions.

use Wandi\EasyAdminPlusBundle\Controller\AdminController as WandiController;
use AlterPHP\EasyAdminExtensionBundle\Controller\AdminExtensionControllerTrait as AlterPHPTrait;

class CustomAdminController extends WandiController
{
    use AlterPHPTrait;
    //....
}

I will try to contact other developer such as Wandi to try and do the same and it will make it better for EasyAdmin users to use multiple extensions.

I contacted the author of Wandi Extension Bundle and he accepted a similar PR so now it's very easy to use both extension :

use EasyCorp\Bundle\EasyAdminBundle\Controller\EasyAdminController;
use Wandi\EasyAdminPlusBundle\Controller\AdminControllerTrait as WandiTrait;
use AlterPHP\EasyAdminExtensionBundle\Controller\AdminExtensionControllerTrait as AlterPHPTrait;

class CustomAdminController extends EasyAdminController
{
    use AlterPHPTrait;
    use WandiTrait;
    
    //...
}

Now it's very easy to use both extension, I just had to override the isActionAllowed used by both extensions and everything is working fine.
