Hi VS Code dev here 👋

1. Have python extension installed, workspace without a launch.json.
2. Do not open a python file
3. Press "Open launch.json" in the Debug viewlet
4. Python options are not presented 🐛

The issue for this is because Python extension did not get activated since no python file got opened.
I suggest that python extension gets activated also for onDebugInitialConfigurations event. This event is fired when the launch.json is about to get populated for the first time.
