[6.x] No way of appending config fields with a section title

[ryanmitchell]

Bug description

With the new layout there is now no way to append a config field that has a section title... compare:

The 'A/B test' is a new field, but it looks lonely without a nice section heading.

When I append a config field to a select input it gets worse, as it gets bundled with other fields:

How to reproduce

        Text::appendConfigField('my_field', [
            'type' => 'toggle',
            'display' => __('My Field'),
            'default' => true,
        ]);
