feat: use expo router

[ElenaBitire]

What does this do?

Update the starter to use expo-router instead of navigation system

Why did you do this?

Expo router provides a simple and declarative way to handle navigation.

Who/what does this impact?

Expo Router has the ability to statically type routes automatically. This ensures you can only link to valid routes and that you can't link to a route that doesn't exist.

How did you test this?
