Upgrade CI images to Ubuntu 24

Libboost went from 1.74.0 to 1.83.0 alongside Ubuntu update.
GCC version is set as default to be more practical.
In Ubuntu22, apt sources were in .list files, in Ubuntu24 they are in .sources files.
Add --break-system-packages for pip installation to use same logic as before, see the pip update 23.0.1 (2023-02-17).
With Ubuntu24 liboai_device requires libpython3.12
