fix array type parsing in DynamicEventPayload::extractValue (#53689)

Summary:
Pull Request resolved: #53689

## Changelog:

[General] [Fixed] - fix array type parsing in DynamicEventPayload::extractValue

When unwrapping event mapping like `e.nativeEvent.touches[0].locationX` e.g. for Animated.event like below,

```
onTouchMove={Animated.event(
  [
    {
      nativeEvent: {
        touches: {
          0: {locationX: animatedValue},
        },
      },
    },
  ],
  {useNativeDriver: true},
)}
```
here it'll throw exception `terminating due to uncaught exception of type folly::TypeError: TypeError: expected dynamic type 'object', but had type 'array'` when getting into folly dynamic array, because array index in the event path is string instead of integer
