Clarify that omarchy-toggle-bar's on/off tracks the bar-off flag (#11803)

on hides the bar and off shows it, matching the literal flag name
rather than an inferred "bar visibility on" reading. The behavior is
correct and depended on by omarchy-toggle-fullscreen-desktop; this
just makes the --help summary say so.
