Unable to debug runtime action from vscode because of invalid .vscode/launch.json

**Describe the bug**
Unable to debug runtime action from vscode because of invalid '.vscode/launch.json' (similar to #244)

The generated .vscode/launch.json look like this (**note the wrong envFile property**).
```
{
"configurations": [
{
"type": "pwa-node",
"name": "Action:wknd-spa-react-0.1.0/ssr",
"request": "launch",
"runtimeExecutable": "${workspaceFolder}/node_modules/.bin/wskdebug",
"envFile": "${workspaceFolder}//Users/johndoe/Downloads/aem-guides-wknd-spa.react.ssr/ui.frontend/dist/application/.env.local",
"timeout": 30000,
"killBehavior": "polite",
"localRoot": "${workspaceFolder}",
"remoteRoot": "/code",
"outputCapture": "std",
"attachSimplePort": 0,
"runtimeArgs": [
"wknd-spa-react-0.1.0/ssr",
"${workspaceFolder}/actions/ssr/index.js",
"-v",
"--disable-concurrency",
"--kind",
"nodejs:10"
]
}
],
"compounds": [
{
"name": "Actions",
"configurations": [
"Action:wknd-spa-react-0.1.0/ssr"
]
}
]
}
```

**To Reproduce**
Steps to reproduce the behavior:
1. Create an AEM Project using [AEM Project Archetype](https://github.com/adobe/aem-project-archetype) with SSR enabled
2. Follow the instructions in `ui.frontend/README.md` to debug AEM SSR via local Docker image of OpenWhisk
3. Run `npm run build-with-ssr`
4. Run `npm run start-ssr-ioruntime`
5. Attach the debugger via provided VS Code Launch configuration and observe the Debug Console

**Expected behavior**
Debugger attaches without any errors.

**Additional context**
Add any other context about the problem here.

Commencez par le .vscode/launch.json généré et les instructions de débogage SSR dans ui.frontend/README.md. Reproduisez le problème avec npm run build-with-ssr et npm run start-ssr-ioruntime, puis suivez la manière dont la configuration de lancement de VS Code est générée. La tâche est terminée lorsque le chemin envFile généré est valide et que le débogueur s’attache sans erreur.
