Components that depend on useIsHeadphonesConnected on Android don't re-render when bluethooth headphones are connected/disconnected.

Summary

useIsHeadphonesConnected hook doesn't trigger re-renderings when BT headphones are connected/disconnected on Android.
This works fine on iOS.

Current behavior

If you have a react component that uses this hook, it will not re-render anything that depends on the value of this hook on Android, when you connect/disconnect BT headphones.

Expected behavior

I can provide an example if that is helpful.

Hi there! A PR would be helpful, this isn't a use case of mine so someone will have to determine the root cause and code up a fix

I have a similar issue on Android, useIsHeadphonesConnected does not trigger any event at all. I use

const deviceInfoEmitter = new NativeEventEmitter(NativeModules.RNDeviceInfo);
const listener = deviceInfoEmitter.addListener('RNDeviceInfo_headphoneConnectionDidChange', (headphone) => { ... })

instead.
