Add cwd setting

[ndan]

I have multiple rails projects in my working folder, but I'm getting [Bundler::GemfileNotFound] Could not locate Gemfile when I'm trying to run debugger.

Example of my project structure:

/my_project
  /frontend
  /api
    /app
    /config
    ...
    Gemfile

Debugger settings:

{
  "type": "ruby-debug",
  "request": "launch",
  "name": "Rails: api",
  "program": "${workspaceFolder}/api/bin/rails",
  "programArgs": [
    "s",
  ],
  "useBundler": false
}

It seems cwd setting might solve the problem by pointing debugger to the right directory.
