title: How to add virtual environment to VSCode Launch.json
body: <p>As the title suggests, I'm using the VSCode debugger to launch a django app.  I created the virtual env using <code> python3 -m virtualenv venv</code> and it's shown below in the place I'd like to have it.  I've checked the VSCode django and debugging tutorials but am no closer to an answer than I was when I started.</p>

  <p>Where do I need to put the <code>source venv/bin/activate</code> command in my launch.json file  below to have it run when starting the VSCode debugger?</p>
