[CI] Build the nightly on Ubuntu 22.04 (#16489)

Precommit uses the nightly compiler to build, and user branches not
merged into HEAD won't build on 24.04, so we get a glibc error because
the nightly was built on 24.04 but the current job is running on 22.04.

Build the nightly on 22.04 to not break precommit and anyone using the
nightly images directly.
