[tvOS] Focus not restoring with sidebarAdaptable

### Before submitting a new issue

- [x] I tested using the latest version of the library, as the bug might be already fixed.
- [x] I tested using a [supported version](https://github.com/reactwg/react-native-releases/blob/main/docs/support.md) of react native.
- [x] I checked for possible duplicate issues, with possible answers.

### Bug summary

When closing sidebar on tvOS it automatically focuses on first visible object on the screen, not the previously focused one.

### Steps to reproduce

1. Create navigator with sidebarAdaptable enabled
2. Create page with multiple Pressable in

### Reproducible sample code

```js

({ sfSymbol: 'star.fill' })
}}
component={(Test)} />

...

{Array.from({ length: 20 }).map((_, i) => (


Button {i}


))}

```

Bắt đầu bằng cách tái hiện sidebarAdaptable navigator example trên tvOS, tập trung vào một control trong ScrollView trước khi đóng sidebar. Truy vết các điểm vào xử lý focus được sử dụng khi sidebar đóng; issue không nêu file hoặc test nào. Được xem là hoàn tất khi focus quay lại object trước đó đã được focus, thay vì object hiển thị đầu tiên.
