Suggestion: Change config name to start with "Debugpy" instead of "Python" when using automatically generated configs

Testing #36

This is a suggestion for consistency. When you create a debug config in launch.json for Debugpy, the config names have Debugpy with a prefix instead of Python, which I like:

But when using automatic configurations, the configs show up with a "Python" prefix, which can be confusing if you also open automatic configs generated by the Python extension, as the entries are duplicated:

If we could rename the ones generated by Debugpy to start with Debugpy, I think it would be better.
