Enable QStyle::State_Horizontal when initializing QStyleOptionProgressBar

Since by default QStyleOptionProgressBar is initialized with initialize
QStyle::State_Horizontal, the example shouldn't overwrite the state, and
instead OR other states into it. Otherwise, the progressbar will be laid
out vertically.

Fixes: QTBUG-100067
