BackHandler.removeEventListener issue for React Native 0.77 version and above

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used [patch-package](https://github.com/ds300/patch-package) to patch `native-base@3.4.28` for the project I'm working on.

Here is the diff that solved my problem:
**Original Issue**
```original
useEffect(() => {
let backHandler = () => {
callback();
return true;
};

if (enabled) {
BackHandler.addEventListener('hardwareBackPress', backHandler);
} else {
BackHandler.removeEventListener('hardwareBackPress', backHandler);
}
return () =>
BackHandler.removeEventListener('hardwareBackPress', backHandler);
}, [enabled, callback]);
```

**Solution**
```diff
useEffect(() => {
let backHandler = () => {
callback();
return true;
};

if (!enabled) return;

const backListener = BackHandler.addEventListener('hardwareBackPress', backHandler);

return () => backListener.remove();

}, [enabled, callback]);
```

This issue body was [partially generated by patch-package](https://github.com/ds300/patch-package/issues/296).

Start by locating the BackHandler.addEventListener usage shown in the issue and review how its cleanup is handled in React Native 0.77 and above. Update the listener cleanup to use the returned subscription's remove method, then verify that enabling, disabling, and component unmounting no longer leave a back-handler listener active.
