Add a .vscode/launch.json file to the default project template to ease out-of-the-box debugging in VSCode

This is the configuration we generally use to start a debug session:

{
  "version": "0.2.0",
  "configurations": [
    // Runs npx boost -e local
    {
      "command": "npm run build && npx boost start -e local",
      "name": "Start Debug Server",
      "request": "launch",
      "type": "node-terminal",
      "cwd": "${workspaceFolder}"
    },
  ]
}
