Cleanup: pass const-reference to RulerItem2::setPlotInfo()

Instead of passing a pointer, pass a cons reference. This is more
idiomatic and consistent with RulerNodeItem2::setPlotInfo().

Also make the reference passed to RulerNodeItem2::setPlotInfo()
const, to make clear that the argument is copied.
