FAB.Group causes DOM nesting warning on web platform: <button> inside <button>

### Current behaviour
When using the FAB.Group component from react-native-paper within an Expo project, a console warning is displayed:
```
LogBox.web.js:104 Warning: validateDOMNesting(...): cannot appear as a descendant of .
```
This warning suggests that there's an issue with the nested structure of button elements within the FAB.Group component.

### Expected behaviour
The FAB.Group component should render correctly without producing any DOM nesting warnings related to button elements.

### How to reproduce?
Create a new Expo project using the provided minimal setup.
Implement a screen with a FAB.Group component as shown in the BugFABExample component.
Run the project on web (expo start --web).
Open the browser console to observe the warning.

Here's a simplified code snippet demonstrating the issue:

```jsx
import * as React from "react";
import { View } from "react-native";
import { FAB, Portal } from "react-native-paper";

const BugFABExample = () => {
const [open, setOpen] = React.useState(false);

return (


{} },
{ icon: "email", onPress: () => {} },
]}
onStateChange={({ open }) => setOpen(open)}
/>


);
};

export default BugFABExample;
```

### Preview


### What have you tried so far?
- Verified that the issue occurs in a minimal Expo project setup.
- Confirmed that the warning is specific to the web platform.

### Your Environment

| software | version
| --------------------- | -------
| ios | x
| android | x
| react-native | 0.74.5
| react-native-paper | 5.12.5
| node | x.x.x
| npm or yarn | x.x.x
| expo sdk | 51.0.28

Bắt đầu bằng việc tái hiện BugFABExample sử dụng FAB.Group và Portal trong một dự án Expo tối giản, sau đó chạy dự án bằng `expo start --web` và kiểm tra cấu trúc button được render. Hoàn tất khi nền tảng web không còn ghi lại cảnh báo validateDOMNesting đối với các phần tử button lồng nhau.
