Use rendered entity as content source

mortona2k → changed the visibility of the branch master to hidden.

I added a patch for altering the content before extracting tags.

In a custom hook, I rendered the entity and stripped tags to get the full text including paragraphs and layout builder content.

This works for now, but a better way to go would be to create a new plugin for the field widget. It's tricky because the javascript loads values from the form to pass to the controller.

Some additional logic might be needed, like a way to ignore certain fields or values that might be more like labels and not relevant for content tags.
