Pull Request Overview

This PR updates the PowerShell script used for setting up npm registry configuration. The changes improve the script's functionality by adding authentication token configuration and fixing file formatting.

• Update .npmrc file creation with proper newline formatting
• Add authentication token configuration for Autodesk npm registry
• Remove unnecessary quotes around parameter values for cleaner syntax

[Copilot]

The authentication token is being written to the .npmrc file without validation that the NPM_TOKEN environment variable exists. This could result in a malformed .npmrc file with 'undefined' or empty token values. Consider adding a check to ensure NPM_TOKEN is set before writing the auth configuration.
