Fix: update FadeInView example to use Animated.Value

[DhruvTheDev1]

Addressed #4654

• The animation example for TypeScript uses const fadeAnim = useAnimatedValue(0); which is not a real function in the React Native API.
• TypeError: (0 , _reactNative.useAnimatedValue) is not a function
• Replaced const fadeAnim = useAnimatedValue(0); with const fadeAnim = new Animated.Value(0);
• Removed useAnimatedValue import
• However the original code does work when scanning the QR code for Expo - perhaps due to some internal support? However the code changes still works and fixes the error.

@cortinico Hi! Is the code change okay as it is const fadeAnim = new Animated.Value(0); or shall I change it to const fadeAnim = useRef(new Animated.Value(0)).current and add the useRef import?
Based on this - I will update the versioned docs too.

@cortinico Hi! I've updated the code to const fadeAnim = useRef(new Animated.Value(0)).current and added the useRef import. Let me know if it looks good.

Hey @DhruvTheDev1, thanks for working on the fix, and sorry for missing this earlier!

The animation examples should have been fixed now across all pages, and in versioned docs. Please let me know if there are still any issues, or just open a new report/PR, happy to review and ship it! For now, I'm closing this as done.
