octavePackages: add automatic updating script based on Python's

This script is heavily based on the script used to update all python
libraries at
pkgs/development/interpreters/python/update-python-libraries/update-python-libraries.py

The Octave Packages' website uses YAML as their basis, so we must
reformat to use YAML instead of JSON.
