Update documentation

[piscopancer]

• In the docs local .db file is used. This piece of code is very illustrative but does not reflect the real world scenario. Provide an example of connecting to a real-life db hosting service like Turso, Supabase or Vercel. If you suggest that it's possible to connect to Turso you need an adapter, but react native's PrismaClient has to option to provide an adapter unlike regular PrismaClient which is confusing
• State it that Expo Go is not supported and app needs to be run via dev client

Thanks
