Thank you for the contribution, really good change. @Vineg how one can verify correctness?

@akosyakov I checked that node js simple app configuration such as

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  "version": "0.2.0",
  "configurations": [
      {
          "type": "node",
          "request": "launch",
          "name": "Launch Program",
          "program": "${workspaceFolder}/app.js"
      }
  ]
}

starts fine on windows.

It caused

Attribute 'program' does not exist ('{path}').

error before.

I am trying this now.

I have verified the ${workspaceFolder} and ${file} on both Windows and Linux (Gitpod):

• on Windows, it is broken on the master,
• and it works as expected with the proposed changes.

👍 Thank you for your help, @Vineg!
