[Feature] DI IDE completion hints improvement

[szymekjanaczek]

Hi,
Maybe it would be useful to add this small modification to Phalcon\Di\DiInterface and Phalcon\Di\Di class?

/**
 * @template T
 * @param string|class-string<T> $name
 * @param mixed $parameters
 * @return mixed|T
 */
public function get(string $name, $parameters = null): mixed
{
    …
}

having this modified, it is possible to use IDE completion hints, if registered a service using class-string:

$di->set(MyClassInterface::class, MyClass::class);

$di->get(MyClassInterface::class)->…here method completion hints from IDE should appear…

I've prepared a PoC in related PR, but since changes should be done in Zephir I'm not sure how to obtain this: doc-block in Zephir looks a bit different.

What do you think about this change?
