app-navigator should be observer component to detect MST

[MusabBasheer]

What's going on? app-navigator does not listen to MST changes

Steps to reproduce

1. use any store inside app-navigator
2. inside app-navigator UI use store prop to show UI based on conditions like {authenticationStore.isAuthenticated ? <AppStack/> : <AuthStack /> } 3- observe no change happened when store prop value changed.

We bumped into this issue as well with swapping stacks. AppNavigator currently does not re-render. Likely related: https://stackoverflow.com/questions/71257766/rerender-appnavigator-on-state-change
