It is very tedious to increase/decrease ColorSlider, Slider, RangeSlider on iOS w/ VO

# 📝 Feedback

ColorSlider/ColorArea/ColorWheel increases/decreases by only 1 on each swipe up/down when using voiceover on iOS. There doesn't seem to be any way to increase this increment. This makes it very tedious to increase/decrease the value.
You can use tap and hold to move the slider but there is no audible feedback on the new value when using this method so it doesn't really work well.

## 🧢 Your Company/Team

Start by reproducing the behavior in the linked ColorSlider example using Safari on iOS with VoiceOver. Trace the ColorSlider, ColorArea, and ColorWheel entry points to determine how swipe increments and audible value feedback are handled. Done means the controls support a less tedious adjustment flow with useful feedback under VoiceOver.
