Tweak default ProceduralSkyMaterial and PhysicalSkyMaterial appearance

Browse Source 
- Tweak colors to be less saturated and more balanced (in terms of hue).
  The cool blue sky is balanced by a warm brown ground,
  which makes reflections look closer to how they'd look like when using
  an HDRI panorama texture.
- Make the ground color dark on both ProceduralSkyMaterial and
  PhysicalSkyMaterial to reduce indoor light leaking, especially
  when using GI.
- Tweak the PhysicalSkyMaterial colors to be as close as possible
  to ProceduralSkyMaterial (with the default sun orientation).
- Tweak editor environment defaults to be identical to the default
  ProceduralSkyMaterial colors. Previously, the default editor sky
  color was different from the colors of a newly created
  ProceduralSkyMaterial resource.

Both new skies were tested without GI, with SDFGI and with VoxelGI.
They were tuned to look best when using ACES tonemapping with a
whitepoint set to 6, but they still look good with other
tonemapping operators.
