Change touch-action wording, add touch-action to examples

Thanks @srmagura but I suggest you to change readme files with informing usage of either PointerSensor or TouchSensor instead of recommending touch-action: none;.

TouchSensor works pretty fine on mobile devices and PointerSensor works pretty fine on web devices. No need to manipulate touch-action CSS property on touch devices because it causes different issues like unable to sorting or scrolling properly etc.

Problem can be simply solved by detecting target device and determining which sensor to be used. I prefer to see this in the documentation explained with your sight.

See detailed example case and my screenshot on https://github.com/clauderic/dnd-kit/issues/435#issuecomment-1880448983
