add debug statements to debugger shell launching path

[vzaidman]

Summary: There's a bug in Node.JS: https://github.com/nodejs/node/issues/51018 where spawning a process on Windows with detached mode and unref will not actually inherit stdio. You need to manually pipe these to get to see stdout and stderr. It works well on MacOS though.
