[TypeDeclaration] Add TypedPropertyFromContainerGetSetUpRector

[TomasVotruba]

Adds a new rule that promotes a private test-case property to a strict typed property based on its @var object type, when the property is assigned via a container fetch in setUp().

Only applies when all hold:

• class is a PHPUnit test case
• property is private, non-static, untyped, single
• has a @var tag whose type is an existing object type
• assigned in setUp() via a container ->get() fetch (static::getContainer()->get(), $this->container->get(), $this->get())

The @var tag is removed after promotion.

 final class BulkNotificationTest extends MauticMysqlTestCase
 {
-    /**
-     * @var BulkNotification
-     */
-    private $bulkNotification;
+    private BulkNotification $bulkNotification;

     protected function setUp(): void
     {
         parent::setUp();
         $this->bulkNotification = static::getContainer()->get('mautic.integrations.sync.notification.bulk_notification');
     }
 }

Registered in TypeDeclarationLevel just above TypedPropertyFromAssignsRector so it applies sooner.
