Summary:
Made link to a page more consistent with the linking style used throughout this file [e.g `hitSlop` and `TouchableNativeFeedback`], I almost missed the `'(See docs)'` link.
`TouchableNativeFeedback` was pointing to the wrong URL.
N/A
* [DOCS] [BUGFIX] [ImprovingUserExperience.md] - Adjusted link for `KeyboardAvoidingView`
* [DOCS] [BUGFIX] [ImprovingUserExperience.md] - Fix `TouchableNativeFeedback` URL
