Cannot set the `spinner` default props of Button

### Description

I'm not sure if this is a bug, or if it's intentional.

### CodeSandbox/Snack link

https://codesandbox.io/s/beautiful-wilson-volfmw?file=/src/theme/index.tsx

### Steps to reproduce

1. set default props of Button
```javascript
const theme = extendTheme({
config: {
// Changing initialColorMode to 'dark'
initialColorMode: "dark"
},
components: {
Button: {
defaultProps: {
spinner: loading...
}
}
}
});
```

2. use the Button
```jsx

```

the default `spinner` is not working.

### NativeBase Version

3.4.28

### Platform

- [X] Android
- [ ] CRA
- [ ] Expo
- [X] iOS
- [ ] Next

### Other Platform

_No response_

### Additional Information

Update this line of source code: https://github.com/GeekyAnts/NativeBase/blob/master/src/components/primitives/Button/Button.tsx#L100

It works fine.

```javascript
const spinnerElement = spinner || resolvedProps.spinner ? (
spinner || resolvedProps.spinner
) : (

);
```

Open src/components/primitives/Button/Button.tsx around line 100 and compare the Button's isLoading behavior with the defaultProps example in the issue. Reproduce it using the linked CodeSandbox or the provided theme and Button snippets. Done means a Button using isLoading renders the configured default spinner on Android and iOS.
