Update Sliders example

Simplify the "responsive layout" implementation. Just use a QBoxLayout
with changing direction instead of repopulating a QGridLayout, and
change the orientation of one set of sliders instead of creating two
sets in a stacked layout.

Simplify the resizeEvent() implementation accordingly.

Update the documentation snippet text to match the code, and document
the resizeEvent() override.
