[IOS] Swift Compilation Error in NewTabView.swift - Generic Parameter Inference Failure

### 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 building an iOS project with react-native-bottom-tabs, compilation fails with Swift type inference errors in NewTabView.swift. The issue occurs on iOS 26.0+ code paths related to @Environment key paths.

### Steps to reproduce

### **Steps to Reproduce**
Install react-native-bottom-tabs in a React Native project with Xcode 16.4+

Build iOS project
Observe compilation fails with Swift errors

**Expected Behavior**
The project should compile successfully without Swift type inference errors.

**Actual Behavior**
Compilation fails with the following Swift compiler errors:

```
❌ (node_modules/react-native-bottom-tabs/ios/TabView/NewTabView.swift:100:4)
100 | @Environment(\.tabViewBottomAccessoryPlacement) var tabViewBottomAccessoryPlacement
| ^ generic parameter 'T' could not be inferred

❌ (node_modules/react-native-bottom-tabs/ios/TabView/NewTabView.swift:100:16)
100 | @Environment(\.tabViewBottomAccessoryPlacement) var tabViewBottomAccessoryPlacement
| ^ cannot infer key path type from context; consider explicitly specifying a root type
```

### **Code Location**
```
The error occurs in node_modules/react-native-bottom-tabs/ios/TabView/NewTabView.swift, lines 98-103:

swift
@available(iOS 26.0, *)
struct BottomAccessoryRepresentableView: PlatformViewRepresentable {
@Environment(\.tabViewBottomAccessoryPlacement) var tabViewBottomAccessoryPlacement // Line 100
var view: PlatformView

func makeUIView(context: Context) -> PlatformView {
// ...
}
}
```

### Note from the reporter:
I'm not very familiar with Swift/SwiftUI development, so I don't know what more to provide here. I'm happy to provide more details, logs, or help test any proposed solutions to resolve this issue!

node_modules/react-native-bottom-tabs/ios/TabView/NewTabView.swift の98〜103行付近から始め、報告された構成で Xcode 16.4+ を使用して iOS ビルドを再現します。iOS 26.0+ の @Environment 宣言と関連する型を調査し、Swift が key-path の型を推論できない理由を特定します。プロジェクトがこれらの Swift コンパイルエラーなしでビルドできれば完了です。
