.SYNOPSIS
Updates the vcpkg port for DirectXMath to match a GitHub release.

.DESCRIPTION
This script updates the vcpkg port at D:\vcpkg\ports\directxmath to match a specific
GitHub release by tag. It updates the version-date in vcpkg.json and the tag and SHA512
hash in portfile.cmake for the source archive.

.PARAMETER Tag
The GitHub release tag (e.g., 'may2026', 'mar2026'). Defaults to the latest tag.
