Py API Docs: Remove older GPUOffScreen example

I think this example does not belong into the api docs and certainly not in the place where it was until now.
Maybe this can become a template in Blender but personally I don't see much value in it as an "official example" because it is hard to see what is going on exactly.
There are a few other examples that show how to use the GPUOffScreen object now.
