[iOS] The scroll position of the multiline TextInput affects the ScrollView auto-scroll when the keyboard opens/closes

Description

On iOS, when using a ScrollView with automaticallyAdjustKeyboardInsets and a multiline TextInput, the scroll position of the TextInput affects how the ScrollView auto-scrolls when the keyboard opens or closes.

Steps to reproduce

<ScrollView automaticallyAdjustKeyboardInsets>
   // Any content above the TextInput to position it at the bottom of the screen
   <TextInput multiline style={{ height: 100 }} /> // multiline TextInput with fixed height and many lines of text (let say 20)
   // More content to allow the ScrollView to scroll if needed
</ScrollView>

1. ScrollView with automaticallyAdjustKeyboardInsets
2. Content above the TextInput to fill the screen
3. Multiline TextInput with fixed height and many lines of text
4. Content below the TextInput to allow the ScrollView to scroll if needed
5. Focus on the input and scroll it to the end
6. Scroll the ScrollView to align the TextInput at the bottom of the screen
7. Focus on the last line in the TextInput
8. The keyboard slides up, and the ScrollView scrolls too much
9. With the keyboard open, scroll the ScrollView to align the TextInput at the bottom of the screen (above the keyboard)
10. Close the keyboard
11. The ScrollView scrolls up

Comienza con el reproducer obligatorio de iOS Snack y compara el comportamiento de ScrollView y multiline TextInput al abrir y cerrar el teclado. Rastrea el manejo de automaticallyAdjustKeyboardInsets y verifica después que ScrollView ya no se desplace demasiado al abrir el teclado ni se desplace hacia arriba al cerrarlo.
