Python launch config is deprecated (#1465)

## Changes
`debugpy` is the new python debugger, and `python` launch config type is

https://marketplace.visualstudio.com/items?itemName=ms-python.debugpy

Python extension already depends on it, but I'm still adding it as an
explicit dependency to our extension too


## Tests
Manual testing
