add clarification about forget method return value

[browner12]

the wording here is just a little unclear. the first sentence seems to suggest that the forget() method does not return anything, even though it does.

you are free to assign the result to a new variable even though you don't need to (and maybe shouldn't?)

$collection = collect(['name' => 'taylor', 'framework' => 'laravel']);
 
$newCollection = $collection->forget('name');

dump($collection === $newCollection); // true
