Customizing Components, old variant values ​​cannot be overwritten

### Description

I want to edit the available variants (ghost, outline, solid, ...) but it doesn't seem to work

### Steps to reproduce

```
import {extendTheme} from 'native-base';
import Button from './button';

export const theme = extendTheme({
components: {
Button: {
defaultProps: {
colorScheme: 'primary',
variant: 'rounded', //If I set the value here as rounded it works, and solid doesn't work, it reuses the old solid configuration
},
variants: {
rounded: ({colorScheme}: InterfaceButtonProps) => {
return {
bg: `${colorScheme}.400`,
}
},
solid: ({colorScheme}: InterfaceButtonProps) => {
return {
bg: `${colorScheme}.700`,
}
}
}
}
},
});

export default theme;
```
