Update to Symfony 6.4

After upgrade, I can't see any direct deprecation in our code.

These are the **indirect deprecations**:

```
Remaining indirect deprecation notices (47)

  44x: Subscribing to postConnect events is deprecated. Implement a middleware instead.
  (Connection.php:387 called by Connection.php:452, doctrine/dbal#5784, package doctrine/dbal)
    10x in BlogControllerTest::setUp from App\Tests\Controller\Admin
    5x in DefaultControllerTest::tearDown from App\Tests\Controller
    4x in BlogControllerTest::testNewComment from App\Tests\Controller
    2x in AddUserCommandTest::testCreateUserNonInteractive from App\Tests\Command
    2x in AddUserCommandTest::testCreateUserInteractive from App\Tests\Command
    ...

  1x: Since symfony/monolog-bridge 6.4: The "Symfony\Bridge\Monolog\Logger" class is deprecated,
  use HttpKernel's DebugLoggerConfigurator instead.
    1x in AddUserCommandTest::testCreateUserNonInteractive from App\Tests\Command

  1x: The "Monolog\Logger" class is considered final. It may change without further notice
  as of its next major version. You should not extend it from "Symfony\Bridge\Monolog\Logger".
    1x in AddUserCommandTest::testCreateUserNonInteractive with data set #0 from App\Tests\Command

  1x: Subscribing to postConnect events is deprecated. Implement a middleware instead.
  (Connection.php:387 called by Connection.php:1654, doctrine/dbal#5784, package doctrine/dbal)
    1x in UserControllerTest::testEditUser from App\Tests\Controller

Other deprecation notices (44)

  44x: In ORM 3.0, the AttributeDriver will report fields for the classes where they are declared.
  This may uncover invalid mapping configurations. To opt into the new mode today, set the
  "reportFieldsWhereDeclared" constructor parameter to true.
  (AttributeDriver.php:78 called by App_KernelTestDebugContainer.php:816, doctrine/orm#10455, package doctrine/orm)
    10x in BlogControllerTest::setUp from App\Tests\Controller\Admin
    5x in DefaultControllerTest::tearDown from App\Tests\Controller
    4x in BlogControllerTest::testNewComment from App\Tests\Controller
    2x in AddUserCommandTest::testCreateUserNonInteractive from App\Tests\Command
    2x in AddUserCommandTest::testCreateUserInteractive from App\Tests\Command
