Building base image for recent CUDA versions

WH

DSS documentation states that base images can be built with `dssadmin build-base-image --cuda-version X.Y` which only supports CUDA versions up to 11.2.

Documentation goes on to say `If you require other CUDA versions, you would have to create a custom image.`

As CUDA 11.2 is more than 3 years old, we'd like to see whether a more recent version of CUDA can be used instead, to keep pace with our other dependencies.

Questions:

1. Are there reasons why more recent versions of CUDA are not supported?
2. Are there plans to support more recent versions of CUDA?
3. What are the steps to create custom images to support more recent versions of CUDA?
