Updates Windows VHD base image versions and adds a helper script/Makefile target to refresh those versions via Azure CLI queries.

Changes:

• Bumped multiple base_image_version values in windows_settings.json.
• Added update_windows_base_versions.sh to query the latest Azure Marketplace image versions and optionally update the settings file.
• Added a make update-windows-base-versions target to run the script.

• Suppressing az stderr (2>/dev/null) combined with || true obscures actionable failures (e.g., not logged in, missing subscription/permissions, CLI argument errors). Consider preserving and surfacing errors (e.g., capture stderr and print it when latest_version is empty) so operators can distinguish 'no versions found' from 'query failed'.
