Code Review

This pull request adds support for NVIDIA H200 NVL GPUs by defining it in stackhpc-compute.yml and adding a corresponding release note. The changes are straightforward and correct. I've provided a couple of minor suggestions to improve consistency and fix a grammatical error.

For better clarity and consistency with other GPU definitions in this file (e.g., h100_80_sxm, a100_80_sxm), it would be more descriptive to name this entry h200_nvl instead of just h200. This makes it clear that this definition is for the NVL variant of the H200 and avoids potential ambiguity if other H200 variants are added in the future.

  h200_nvl:
    resource_name: "{{ h200_nvl_resource_name | default('h200_nvl') }}"
