Add field_group schema patch

See https://www.drupal.org/project/field_group/issues/3409719

I'm seeing this deprecation notice

8x: The definition for the 'core.entity_form_display.node.localgov_services_landing.default.third_party_settings.field_group' sequence declares the type of its items in a way that is deprecated in drupal:8.0.0 and is removed from drupal:11.0.0. See https://www.drupal.org/node/2442603 8x in TopicListBuilderTest::testTopicListBuilderParagraphDisplay from Drupal\Tests\localgov_services_sublanding\Functional

Lots of times when running tests. Looks like there is an issue and patch for it (though no recent release?)
