Updated Blendfile of Godray Tutorial

Hi, one of you asked for a solution for the intersection between the ray and objects. I implemented an ambient occlusion based mask that will blur out hard, intersecting edges. It does not account for objects blocking paths of the light, it will only ever be an approximation of volumetric light (even though blocking may theoretically possible... Have to think on that one a bit).

I added a new slider in the geonode settings to dial the effect in and out. File was made and tested on both Eevee and Cycles in Blender 4.1. I can't guarantee it running on older Versions.

It at least hot-fixes the issue for now.
