NVIDIA runtime doesn't show up in Docker snap on Ubuntu Core 22

I have installed Ubuntu Core 22 on a pc that has a NVIDIA 3090 GPU. Previously, this worked fine with Docker when I had Ubuntu server installed but since moving to Ubuntu Core 22, I have not been able to see the nvidia runtime in the docker snap. Also, the output of `lspci` (included below) seems to indicate that it hasn't recognized it as a 3D Controller. Since I don't see any issues, perhaps I am missing a step?

### Some relevant info

Start with the Docker snap logs and the `nvidia-core22` and `nvidia-assemble` installation details included in the report, especially the missing `libcuda.so.535.161.08` CDI error. Trace how the Docker snap discovers NVIDIA driver libraries on Ubuntu Core 22 and compare that with the assembled device files; done means Docker reports an NVIDIA runtime and the CDI generation error is resolved.
