Subject: [PATCH] Map DOMDocument::class to Gt\Dom\HTMLDocument::class (#449)

* Map DOMDocument::class to Gt\Dom\HTMLDocument::class

Fixes `DOMDocument::registerNodeClass(): Argument #2 ($extendedClass) must not be an abstract class` from change in PHP 8.1.26

* Map DOMDocument::class to static::class

Ensures DOMDocument is always mapped to the class that extends abstract Gt\Dom\Document
