On Qubes the conversion in dev mode would fail when converting from a Fedora 38 development qube via a Fedora 39 disposable qube. The reason was that dz.ConvertDev was receiving `.pyc` files, which were compiled for python 3.11 but running on python 3.12. Unfortunately PyZipFile objects cannot send source python files, even though the documentation is a little bit unclear on this [1]. Fixes #723 [1]: https://docs.python.org/3/library/zipfile.html#pyzipfile-objects

Our
dz.ConvertDevQubes policy, which runs in a disposable qube, expects a Python zipfile. This zipfile is created in the dev qube where the./dev_scripts/dangerzone*command runs, and it contains the Python compiled files for thedangerzone.conversionmodule.The problem here is that the disposable qube and the main qube may have different Python versions. This can happen if e.g., the dev qube is based on Fedora 38 (Python 3.11), and the disposable qube is based on Fedora 39 (Python 3.12).
