Summary

As the Gutenberg Engaging Networks plugin is no longer used, any mention to it in the codebase has to be removed and the following condition has to be replaced:

if (is_plugin_active('planet4-plugin-gutenberg-engagingnetworks/planet4-gutenberg-engagingnetworks.php')) { ... } 

Instead, that condition has to be updated to look for the EN Form feature flag, since that functionality still exists.
