ci: Update build container images to Ubuntu 24.04

[agherzan]

This fixes the latest Python version requirement.

we might need to tweak the system apparmor policy see

https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2056555

here is what worked for me on 24.04

   sudo tee /etc/apparmor.d/bitbake > /dev/null <<'EOF'
   abi <abi/4.0>,
   include <tunables/global>
   profile bitbake /**/bitbake/bin/bitbake flags=(unconfined) {
           userns,
   }
   EOF

then apply it

   # Reload AppArmor Profile
   sudo apparmor_parser -R /etc/apparmor.d/bitbake

Sometimes this may not be enough. Then do below it will compromise apparmor defaults a bit more.

   sudo apparmor_parser -R /etc/apparmor.d/unprivileged_userns

@kraj It doesn't look like it broke due to AppArmor. What do you think of the logs?

interesting, maybe your install does not enable it, but in anycase if thats not being flagged then I am ok with this patch
