Use PHP8 return type instead of annotations

[dennismetz]

API Platform version(s) affected:
I currently use api-platform/symfony in version 4.0.6

Description
The PHP8 return data type of the method is ignored. Only the old notation for annotations is taken into account.
You then get an error message when you call the whole thing via the API platform: Unexpected non-iterable value for to-many relation.

How to reproduce
I call a collection in my entity and only want to return a single item or null from it.

	#[Groups(['Vehicles', 'readVehicle'])]
	public function getDriver(): null|VehiclesDriver // null|VehiclesDriver is completly ignored
	{
		if (0 < count($this->getVehiclesDriver()))
			foreach ($this->getVehiclesDriver() as $driver)
				return $driver;
		return null;
	}

Possible Solution
Currently you can fix the error by returning the return type in the annotation.

	/**
	 * @return VehiclesDriver|null
	 */
	#[Groups(['Vehicles', 'readVehicle'])]
	public function getDriver(): null|VehiclesDriver
	{
		if (0 < count($this->getVehiclesDriver()))
			foreach ($this->getVehiclesDriver() as $driver)
				return $driver;
		return null;
	}

I expect this is an issue from symfony? But it's weird, what property info extractor are registered on your project?
