refactor: Add debug configuration for running Copilot locally

A new debug configuration has been added to the launch.json file. This configuration allows for launching Copilot locally by running the "start" script using npm. It skips files in the "<node_internals>" directory and is specifically configured for debugging Node.js applications. This change improves the development experience by enabling easy debugging of Copilot locally.
