chore: drop the Toggle (slide) exhibit — it is the only toggle now

The variants row shows every further look a widget can take, and the slide
toggle is no longer a further look: cce-ui@98008b0 retires the rocker and
the `style.control.toggle.style` switch, so the named Toggle slot already
is this. `Toggle::with_slide` is gone with it.
