github-actions: python 3.12 is the default when using ubuntu-latest

[v1v]

Proposed commit message

The GitHub runners has been bumped from ubuntu-22 to ubuntu-24 and the default python version has changed from 3.10 to 3.12. See actions/runner-images#10636

For the long run: make check-default should be updated to support 3.12.

This a workaround for:
