🤖 Generated by Copilot at cc09d2c

This pull request simplifies the code and configuration of the codehelper and blobserve components, which are responsible for serving the VS Code web server to the IDE. It removes some unnecessary logic and variables that were used to customize the Open VSX registry URL, which is now handled by blobserve alone.

How to test

• Check vscode web works, webviews, web extension, gp validate, etc

Web extensions are still pulling from open-vsx.org, but it is known right?
