split-out ubuntu 23* versions

since 2023 didn't produce and LTS ubuntu versions

the Ondrej repo we use for installing arbitrary PHP versions doesn't
(easily) support non-LTS versions of ubuntu, which means that 23.04 and
23.10 are problematic using the repo

However, these versions ship with  php8.1 and php8.2 (respectively), so
we don't even need the Ondrej repo for these, so we'll remove it

In general, we'll only support LTS Ubuntu repos because of this, but if
they happen to ship with our preferred PHP versions and otherwise work
w/o heroics, we'll include nominal support in the script

snipeit.sh
