"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
```

首先，在启用 Reduce Transparency 并使用自定义 tabBarStyle backgroundColor 的情况下，在 iOS 上重现该问题。跟踪 tabBarStyle 在 bottom-tabs 实现中的应用方式，并验证启用辅助功能设置后背景色仍保持不变；未提供可复现示例或测试文件。
