Ori Livneh c4ea314470 Fix for create_pygmentize_bundle Python 3 compat
We only support Python 3, but we're still looking for a Wheel file with
python_version starting with 'py2'. This is currently OK because
Pygments is released as a py2.py3 wheel, but it will break when they
remove support for Python 2, which will happen eventually.
