Draft: ci: start using Python 3 with Ubuntu 24.04
When CI jobs run using an Ubuntu container image, a Python package version is selected to be used. With the release of Ubuntu 24.04, Python 2 is no longer available for use and has started causing CI job failures. Start using Python 3 when Ubuntu version 24.04 or greater is used.
