Apply suggested workaround for affected CI test

[glatterf42]

This PR tries to implement the workaround identified in actions/runner-images#11137 for the CI failure on Ubuntu 24.04 with Python 3.12.
I'm not sure which part(s) of the suggested workaround are actually required, some seem to evaluate to no-ops (e.g. libssl-dev is already the newest version (3.0.2-0ubuntu1.18).). I'll play around with the steps to see if the workaround can be made more concise.
