Update make-package-info.py

[maccallum]

This script currently doesn't run, as some of the directories it expects to operate on have been changed. Is this script necessary? Is it necessary to have a script that does this? Or can we just hand-code the package-info.json file?

we should update it and it should be generated. I can do this. Here's a reference.
