Notification on new Chia version

[greimela]

I just saw a nice feature idea on Reddit and wanted to add it here.

It'd be nice if Chiadog could send an alert when a new Chia version became available.

It would especially be helpful for people whose farms run passively in the background and don't pay attention unless the Chiadog barks 🐶
