D N 401f2fbb14 chore: [TS] Transform TouchableHighlight from class to ForwardRef component (#44038)
Summary:
If you check the source of truth `packages/react-native/Libraries/Components/Touchable/TouchableHighlight.js` I'll find that `TouchableHighlight` is a result of `React.forwardRef(...)` :

https://github.com/facebook/react-native/blob/44d59ea6f9a1705487314e33de52f7056651ba25/packages/react-native/Libraries/Components/Touchable/TouchableHighlight.js#L382-L391

So the TS type isn't correct : (

```tsx
<TouchableHighlight ref={ref => {   }} />
//                     ^^^ ref should be a `View` (but now it's `TouchableHighlight`)
```

 ---

**Breaking  changes**

As `TouchableHighlight` isn't class anymore it can't be used as value & type

```tsx
import {TouchableHighlight} from 'react-native';
const ref = useRef<TouchableHighlight>();
//                ^^^ TS2749: TouchableHighlight refers to a value, but is being used as a type here.
//                            Did you mean typeof TouchableHighlight?
```

**Recommend solution:** use build-in react type `React.ElementRef`

```diff
-const ref = useRef<TouchableHighlight>();
+const ref = useRef<React.ElementRef<typeof TouchableHighlight>>();
```

Also, it possible to use `View` as type:

```diff
-const ref = useRef<TouchableHighlight>();
+const ref = useRef<View>();
```
