Add other App Theme options

Map Theme can now be "synced" with App Theme: when App Theme is dark, map is in dark mode, and same with light mode. This feature is very cool. Before this update, I used Sunrise/sunset as Map mode, which I think is the best Map Mode setting.

However, App Theme can only be full day, full night, or automatic (depending on OS Dark Theme).
It is not possible to set it to "Sunrise/sunset" or "Light sensor".

To be completely coherent, it would be great to have these two additional options.
With these settings, app AND map could switch between light/dark modes using sunrise/sunset or using light sensor.

Tell us about the expected behaviour (required)

Add "Sunrise/sunset" and "Light sensor" to "App Theme" configuration.

Sunrise/sunset would use sunrise and sunset times to switch between light and dark app theme.
"Light sensor" would use ambient light to switch between light and dark app theme.

Tell us about alternatives you've considered (required)

The only way to have an equivalence is to set Map Mode to "App Theme", App Theme to "System default" and enable/disable OS Dark Theme on sunrise/sunset or when ambient light is high/low
