Remove comment in packages.config causing powershell parsing error

[Blue (OneBlue)]

Summary of the Pull Request

This change removes the comment in packages.config. Configuring cmake with that comment it places gives:

The configuration still succeeds, but we might as well remove this. It's probably not worth adding complexity to the parsing script to support comments either

Pull request overview

This PR removes an XML comment from packages.config to prevent a PowerShell-based packages.config parsing step (used during CMake configure) from throwing Cannot index into a null array, while keeping NuGet restore/configure behavior unchanged.

Changes:

• Removed a TODO XML comment line from packages.config that was being interpreted as a node by the PowerShell Select-Xml pipeline.
• Eliminated the noisy configure-time PowerShell exception without adding extra parsing complexity.
