New Sky/Atmosphere model in 4.24

[RVillani (Rod Villani)]

Did you try using it from the Sun and Sky actor?
From the preview notes:

**Sun and Sky Actor. **We modified the existing Sun Positioner plugin to wrap a directional light, a sky light, and the newly introduced Atmospheric Sky created by the rendering team. The goal is to provide a workflow similar to the HDRI Backdrop actor added to 4.23, where users are provided with self contained functionality into a single actor.
