Update `phpgt/dom` composer dependency for `magento/magento2-page-builder` extension

[andrewbess]

We checked fatal errors with environment PHP 8. One of the problems is incompatible composer dependency - phpgt/dom in magento/magento2-page-builder extension. We need to upgrade phpgt/dom composer dependency to the next versions "~2.2.1||~3.0.0" and check it again.

Expected result (*)

1. The system has no fatal errors

Actual result (*)

1. Declaration of Gt\Dom\ChildNode::before(DOMNode $node): void must be compatible with DOMElement::before(...$nodes): void in /var/www/html/vendor/phpgt/dom/src/Element.php on line 29
