Subject: [PATCH 2/2] Fix build-cuda-devcontainer: remove NVIDIA CUDA apt
 sources from Dockerfile

The devcontainer build fails intermittently because the nvidia/cuda base image
adds a NVIDIA CUDA apt repository, and when the common-utils devcontainer feature
runs apt-get update, it hits the NVIDIA CUDA repo which can experience temporary
mirror sync issues (e.g., "File has unexpected size... Mirror sync in progress?").

Since CUDA is already provided by the base image and no additional CUDA packages
are installed via apt in the Dockerfile, removing the NVIDIA CUDA apt sources
prevents these intermittent failures without any loss of functionality.

Fixes job: https://github.com/psc-code/psc/actions/runs/26962348562/job/79555760599
