Irradiance volume example tweaks (#11911)

Browse source 
# Objective

Fixes two small quality issues:

1. With the new default ev100 exposure value, the irradiance intensity
was too low
2. The camera was rotating at a fixed speed (instead of a speed
multiplied by delta time), resulting in frame-rate dependent rotation
speed.
