Upgrade to react-navigation 5.X

[tyrauber]

@lezzmo, Thanks for this.

What do you think about upgrading to react-navigation 5.X? This example is currently using the 3.X syntax, specifically createAppContainer which is no longer used in 5.x, replaced with the NavigatorContainer Syntax.

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>{/* ... */}</Stack.Navigator>
    </NavigationContainer>
  );
}

Upgrading from 4.x

Any reason not to keep this current?

Yeah I totally agree.. I believe at the time I built this the react-navigation lib was in beta. I'll try to update the lib.
