should we use a variable so it's only updated in one place?

Greptile Overview

Greptile Summary

This PR attempts to update MatX's development and CI infrastructure to use CUDA 13.0.1, modifying three files: .devcontainer/setup.sh sets the default container version tag, .github/workflows/build-docs.yml updates the documentation build workflow container, and .devcontainer/recipe.py changes the base Docker image and CuPy dependency. These changes are part of a coordinated effort to standardize the project's container environment on a newer CUDA version, ensuring consistency across local development (devcontainer setup), CI documentation builds, and Python package dependencies. The changes follow the project's existing container-based development workflow structure, where .devcontainer/ defines the VS Code development container configuration and GitHub Actions workflows rely on pre-built release containers from ghcr.io/nvidia/matx/release.

Important Files Changed

Filename	Score	Overview
.devcontainer/recipe.py	1/5	Updates base Docker image to nvidia/cuda:13.0.1-devel-ubuntu24.04 and CuPy to cupy-cuda13x, but CUDA 13.0.1 does not exist and will cause build failures
.devcontainer/setup.sh	1/5	Changes default MATX_VERSION_TAG from 12.9.1_ubuntu24.04 to 13.0.1_ubuntu24.04, referencing a non-existent container version
.github/workflows/build-docs.yml	1/5	Updates documentation build container image to ghcr.io/nvidia/matx/release:13.0.1_ubuntu24.04-amd64, which does not exist

Confidence score: 0/5

• This PR will immediately fail and cannot be merged - it references a non-existent CUDA version that will break all container builds and CI workflows
• Score reflects critical blocker issues: CUDA 13.0.1does not exist (current CUDA versions are in the 12.x series), causing Docker image pull failures, pip package installation failures, and complete CI pipeline breakage across all three modified files
• All files require immediate correction - the intended CUDA version should be verified and all references updated to an actual existing CUDA release (likely 12.6.x or similar) before this PR can proceed

but CUDA 13.0.1 does not exist and will cause build failures

Greptile is wrong, CUDA 13.0.1 most certainly does exist.
