Pull Request Overview

This PR removes the dependency on the external @azure/abort-controller package in favor of using the native AbortController that is now available in Node.js runtime. This aligns with the existing practice in the artifact package and reduces external dependencies.

• Removes the import statement for @azure/abort-controller from downloadUtils.ts
• Removes the @azure/abort-controller dependency from package.json
