With migration from ubuntu jammy to noble, python3.11 is not available anymore. This makes the job to fail on pre-install step. So let's use Python 3.12 which is available out of the box on Noble after switch. This also bumps pylint version, as older one does not work anymore with Python 3.12. New pylint brings quite some new rules with it. Some were disabled, some were fixed within this patch. Change-Id: I4ba288966c582910e8a822d4531e29c9c005e48f
