Fix docs for QToolbar's isMovable property default value

The docs stated that by default this property is set to true. However,
that is not exactly precise as this property is by default set to
whatever the current style's styleHint() returns for
QStyle::SH_ToolBar_Movable. That just happens to return true for most
styles. Fix docs to mark this distinction.
