Add azimuth to sun.sun dialog's more-info section

[mattmattmatt]

Proposed change

Add the sun's azimuth attribute to the more info dialog.

The dialog already includes the sun's elevation, and now the azimuth is displayed similarly. Added new translation key and azimuth's unit measurement (degrees, °).
