Tutorials/CUDA C++: Rebase on to CUDA 13.1 container

[brycelelbach]

Rebase the CUDA C++ tutorial from rapidsai-devcontainers-25.10-cpp-cuda12.9 to the nvidia-cuda-13.1.0-devel-ubuntu22.04 base image (CUDA 13.1), and modernize the setup to match the accelerated-python tutorial.

Changes

tutorials/cuda-cpp/brev/dockerfile

• Base image: rapidsai-devcontainers-25.10-cpp-cuda12.9 → nvidia-cuda-13.1.0-devel-ubuntu22.04
• Install Python 3.12 from deadsnakes PPA (base image no longer bundles Python)
• Structured ENV block with PIP_DISABLE_PIP_VERSION_CHECK, VIRTUAL_ENV_DISABLE_PROMPT, updated PATH
• System packages installed with DEBIAN_FRONTEND=noninteractive and comprehensive package list
• Passwordless sudo setup matching accelerated-python
• Docker installation cleaned up
• Use Nsight tools from the CUDA toolkit (/usr/local/cuda/bin/nsys, /usr/local/cuda/bin/ncu)
• Jupyter announcements disabled
• Clean layer ordering: system packages → sudo → Python → Docker → pip → Jupyter config → COPY
