ci: refresh Ubuntu releases and add "latest" alias

Refresh the list of Ubuntu versions used for testing: add new Ubuntu
23.10 and 24.04, while dropping unsupported Ubuntu 23.04 (Lunar).

Add also the "latest" Ubuntu (currently 24.04) just in case we forgot to
roll the releases once new one comes out.
