[go_router] Fix missing build parameter in type-safe routes topic doc…

…umentation (flutter#5040)

Added the missing GoRouterState state parameter to the build methods of `HomeScreenRoute` and `SongRoute`, to the type-safe routes [topic](https://github.com/flutter/packages/blob/main/packages/go_router/doc/type-safe-routes.md).

Using the current documentation (without the fix), raises the error:
``` dart
'HomeScreenRoute.build' ('Widget Function(BuildContext)') isn't a valid override of
'GoRouteData.build' ('Widget Function(BuildContext, GoRouterState)')
```

I didn't find any issue for this, but if you'd want I could simply open one myself and link it to this pull request.
