Incorrect type on DataCollection iterator

[iamrgroot]

Hi! Thanks for v2! I'm loving the upgrades. However, I'm running into the following phpstan error: "Cannot call method validate() on array." in the following snippet:

/** @var DataCollection<int,Data> */
$collection = Data::collection();

foreach($collection as $item) {
    $item->validate();
}

I think this is because the type of BaseDataCollectable -> getIterator is incorrect:

    /**  @return \ArrayIterator<TKey, array> */
    public function getIterator(): ArrayIterator

But should be:

    /**  @return \ArrayIterator<TKey, TValue> */
    public function getIterator(): ArrayIterator

You can see the difference it makes with with the phpstan playground:

• Current: https://phpstan.org/r/21cf5d37-5693-414c-9b11-918e3dd894d6
• Fixed: https://phpstan.org/r/bfd6646f-8c16-4746-9385-5c89ea5e7fd5

Please correct me if I'm using something wrong!

Looks like you're correct! It will be fixed in the next version!
