fix: debug config provider

[kitsonk]

This deals with two issues that were causing challenges when configuring debug:

• There was a static config in the package.json which then causes the debug provider to not actually work.
• The debug provider did not take into account the context, meaning that if you were using an import map, a cache path, or a config file, none of those would be configured to automatically occur when starting debug or generating a launch.json.

In addition, the naming of the launch tasks have been adjusted to be better aligned with Chrome and Node.js debug configurations provided by vscode.
