Improve support doctrine/orm 3.0

After update doctrine/orm to 3.0 version:

PHP Fatal error:  Uncaught TypeError: Doctrine\ORM\Mapping\Driver\XmlDriver::__construct(): Argument #2 ($fileExtension) must be of type string, null given, called in /app/var/cache/dev/ContainerN1ivQrS/App_KernelDevDebugContainer.php on line 889 and defined in /app/vendor/doctrine/orm/src/Mapping/Driver/XmlDriver.php:47

doctrine/orm 3.0:

class XmlDriver extends FileDriver
{
    public const DEFAULT_FILE_EXTENSION = '.dcm.xml';

    /**
     * {@inheritDoc}
     */
    public function __construct(
        string|array|FileLocator $locator,
        string $fileExtension = self::DEFAULT_FILE_EXTENSION,
        private readonly bool $isXsdValidationEnabled = true,
    ) {

doctrine/orm 2.4:

class XmlDriver extends FileDriver
{
    public const DEFAULT_FILE_EXTENSION = '.dcm.xml';

    /** @var bool */
    private $isXsdValidationEnabled;

    /**
     * {@inheritDoc}
     */
    public function __construct($locator, $fileExtension = self::DEFAULT_FILE_EXTENSION, bool $isXsdValidationEnabled = false)
    {

I'm really not sure that my decision is correct
