Subject: [PATCH v9a 21/22] ci: linux: Run on ubuntu-24.04 and define what we run on centrally

From: Andres Freund <[email-masked]>
Date: Wed, 3 Jun 2026 14:04:07 -0400

Centrally define the version of linux runners, to make it easier to update. We
don't just want to use ubuntu-latest, as it's not implausible
