fix: [TypeScript] Allow to pass empty string as style

[retyui]

Summary:

import {Text} from 'react-native'

interface Props {
  foregroundColor?: string | undefined | null
}

function Test({foregroundColor}: Props){
  return <Text style=[styles.icon, foregroundColor && { color: foregroundColor }] />
  // ^^^ Error: Type "" is not assignable to type TextStyle | Falsy | RegisteredStyle<TextStyle> | RecursiveArray<TextStyle...
}

Changelog:

[GENERAL] [ADDED] - [TypeScript] Allow to pass empty string as style

Test Plan:

Change Falsy type locally and test it on the next code

const styles = StyleSheet.create({
  text: {
    color: 'red',
  },
});
export const a = <Text style={[styles.text, null, '', undefined, false]} />;
