"Reduce Transparency" setting issue with tabBarStyle

### 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

In the application I use only dark color and would like to keep the same backGround color for tabBar, everything works fine but when I enable "Reduce Transparency" background color got overwritten, see attached video.

### Steps to reproduce

1. Set backGroundColor for tabBarStyle
2. Open iphone settings -> Accessibility -> Display & Text Size -> turn on Reduce Transparency toggle
3. Open the app -> the color will be overwritten

### Reproducible sample code

```js
don't have this opportunity
```

まず、Reduce Transparencyを有効にし、カスタムのtabBarStyle backgroundColorを設定した状態でiOS上の問題を再現します。bottom-tabsの実装でtabBarStyleがどのように適用されるかを追跡し、アクセシビリティ設定が有効な場合も背景色が変わらないことを確認します。再現可能なサンプルやテストファイルは提供されていません。
