Add a connection troubleshooting section

[TimoPtr]

Based on the request made https://github.com/orgs/home-assistant/discussions/1588. We should add a new page in the troubleshooting section of the settings.

The screen should be made using our best practices described in our developer documentation https://developers.home-assistant.io/docs/android/ (MVVM, tests, coroutines, ...)

Make the composable easy to reuse so that we could potentially integrate this same composable into the error screen.

Make it look nice, with animation for instance while it's checking the connectivity.
