Throws deprecation notice with PHP 8.1

As an alternative we could go into gin_gutenberg_preprocess_html() and switch the condition to

if (_gin_gutenberg_is_gutenberg_enabled($route_entity) && _gin_gutenberg_is_content_form()) {

This will ensure that we're not checking for the content form if gutenberg is not enabled. That also makes more logical sense.

Here's a patch.

Actually it happens on Gutenberg forms as well, so it requires an additional change.

Another try, because patch 4 leads to fatal errors on node pages, where the node object is not upcasted.

Thanks for the patch Stephan, applied to the dev release, will tag a new release sooner or later
