`DOMNode::$childNodes` always contained `DOMNodeList`.
This simplifies the code a bit and will make it slightly easier in case we decide to switch to `foreach` iteration.
This was forgotten in b580cf2.
`DOMNodeList` implements `Traversable`. There are some `for` loops left but we cannot simply replace those: PHP follows the DOM specification, which requires that `NodeList` objects in the DOM are live. As a result, any operation that removes a node list member node from its parent (such as `removeChild`, `replaceChild` or `appendChild`) will cause the next node in the iterator to be skipped. We could work around that by converting those node lists to static arrays using `iterator_to_array` but not sure if it is worth it.
