test-popular-containers: add ubuntu 23.10 and 24.04

Add support for testing Ubuntu 23.10 and 24.04
Remove 23.04 since it is not supported anymore.

The `--timezone=off` parameter is needed as building the rootfs fails
for 24.04 without it, with a conflict that it could not replace
it (probably because systemd-nspawn bind mounts it).
