Hi

Currently

new ClassMetadataInfo(\DateTime::class) is inferred as ClassMetadataInfo<\DateTime> by both psalm and phpstan
new ClassMetadata(\DateTime::class) is inferred as ClassMetadata<\DateTime> by psalm but as ClassMetadata<object> by phpstan

This is related to this phpstan issue https://github.com/phpstan/phpstan/issues/5057
I don't know how and when the issue will be fixed so one way to fix it temporary would be to repeat the constructor:

        /**
	 * @psalm-param class-string<T> $class
	 **/
	public function __construct(string $class)
	{
		parent::__construct($class);
	}

Since you're using phpstan in this project, you might end with this issue while bumping the phpstan level.
Do you prefer I create a PR here or in https://github.com/phpstan/phpstan-doctrine ?
(The second solution won't fix the issue here since you're not using the library here)
