In the preceding commit we've dropped the last job that still used
Ubuntu 20.04. We still had some conditional logic for that specific
image that made us use Python 2 instead of Python 3, but this is dead
code now.
We could of course exercise Python 2 in any of our other CI jobs. But it
reached end of life in 2020 already, and none of the distros that we use
have it packaged anymore. Furthermore, it seems like the world has
finally adapted to Python 3. So it doesn't feel all that useful to still
exercise it.
Drop the logic and instead use Python 3 unconditionally.
