Automatic update from web-platform-tests script: Stop treating `<label>` as a form-associated element `<label>` was being treated as a form-associated element, but the spec[^1] does not list it as one. This led to it being added to `HTMLFormElement::controls`, but not removed consistently. This change stops treating it as a special-case form-associated element which fixes a panic in debug builds.
