make:entity add PHPDoc to Collection (getBars()) getter method for auto-completion

So:

+/**
+ * @return Collection<int, Bar>
+ */
public function getBars(): Collection
{

}

The @return will aid auto-completion and is more correct than saying @return Bar[], which is what we do currently:

maker-bundle/src/Util/ClassSourceManipulator.php

Lines 604 to 610 in 884f10d

	$this->addGetter(
	$relation->getPropertyName(),
	$collectionTypeHint,
	false,
	// add @return that advertises this as a collection of specific objects
	[sprintf('@return %s|%s[]', $collectionTypeHint, $typeHint)]
	);

Hi I would like to contribute if its okay.

$this->addGetter( 
     $relation->getPropertyName(), 
     $collectionTypeHint, 
     false, 
     // add @return that advertises this as a collection of specific objects 
     [sprintf('@return Collection<%s,%s>', $collectionTypeHint, $typeHint)] 
 ); 

the code should look like this?
