Update color-schemes.md

1) bare workflow recommendations for android dont work
```
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    // dont work
    // Intent intent = new Intent("onConfigurationChanged");
    // intent.putExtra("newConfig", newConfig);
    // sendBroadcast(intent);
    
   // works ideally and already approved by many people in issue facebook/react-native#28823 (comment)
   getReactInstanceManager().onConfigurationChanged(this, newConfig);
}
```

2) Turned on debugger break `useColorScheme` and `Appearance.getColorScheme` they always return 'light'
