Bug report

It seems that PHPStan is not reporting missing type hint for:

• Generator
• Iterator
• IteratorAggregate

It works fine for Traversable

Code snippet that reproduces the problem

class Test
{
	public static function generator(): Generator
	{
		yield 'test';
	}
}

https://phpstan.org/r/ea648942-e5e9-4400-b219-07f69ef7465d

Expected output

Method Test::generator() return type has no value type specified in iterable type Generator.
