Flatlist onMomentumScrollEnd called inconsistently between Android and iOS

Description

it seems the behavior isn't consistent between android and ios.

on android it works when you flick and release, it also works when you scroll and hold thereby controlling the scrolling.

on IOS it only works when you flick and let the scroll momentum end by itself.

https://reactnative.dev/docs/scrollview#onmomentumscrollend
Called when the momentum scroll ends (scroll which occurs as the ScrollView glides to a stop).
in this case, i believe it means the behavior is incorrect on Android because it's called when it glides to a stop and when the user controls the stop.
or since there's no specific event for when both the scroll and glide are ended by the user controlling it, we should fix the behavior on iOS to behave the same on Android and update the docs to Called when the momentum scroll ends (scroll which occurs as the ScrollView stops).

Steps to reproduce

1. android: flick and release -> momentum end event called
2. android: scroll and hold at one position then release -> momentum end event called
3. ios: flick and release -> momentum end event called
4. ios: scroll via scrollbar, hold then release -> momentum end event is called
5. ios: flick and release via scrollbar -> momentum end event is called
6. ios: scroll, hold at one position then release -> momentum end event is not called

Start with the linked Snack reproducer and the ScrollView onMomentumScrollEnd documentation, then compare the six Android and iOS reproduction steps. Determine which platform behavior is intended and verify the result against both the new and old architectures. Done means the event behavior is consistent with the agreed semantics and the documentation accurately describes it.
