HemisphereLightNode uses view normals instead of world

[vitro-mod]

Description

HemisphereLightNode uses normalView which causes unwanted color drift when camera angle changes.

This behavior is specific only to WebGPURenderer, therefore I suppose it's a bug.

Reproduction steps

1. Setup a scene using WebGPURenderer with HemisphereLight with different colors and a stationary object
2. Change camera angle
3. Notice some changes in color of object
4. Repeat this with WebGLRenderer
5. Notice that there is no these changes in shading
