Add In-App Update Prompt

[Akash-Ramjyothi]

Feature Request:

If there is an update for Amahi Android App, the only way how users could know about it is the notification from the Play Store. Sometimes, users enable the Auto-Update, but mostly only when connected to Wi-Fi. If there was a way to notify users about the Update inside the app regardless of Wi-Fi or mobile data, whenever a newer version is released, it would be better.
