[web] Fix NativeViewGestureHandler style. (#3070)

## Description

#3041 introduced a regression - calling `updateGestureConfig` resulted
in `NativeViewGestureHandler` having `touchAction: none;` even though it
shouldn't. Because of that our example app didn't scroll.

## Test plan

Check that example app is scrolling.
