Support for MySQL 8.4 (LTS) in Debian 12 & 13

[erikgieseler]

MySQL 8.4 (LTS) packages for Debian 12 and 13 have been available for several months now.

It would be great to have these in Docker images as an alternative to Oracle Linux.
Thank you!

It was an intentional change that 8.0 was the last version to have Debian variants (#867), but I do wonder if that's worth revisiting given things like #1117 🤔

[tianon]

Oh right, we end up having similar issues as #1117 with Debian, as evidenced most obviously by our 8.0 version being stuck on Debian Bookworm (no Trixie packages available).

From an admin perspective, going Oracle Linux only is problematic. If the rest of the stack is already Debian-based, introducing a different base OS just for MySQL adds unnecessary divergence. If MySQL 8.4 Debian packages exist, what prevents continuing Debian-based images as well? Is this mainly maintenance or CI overhead? Supporting both variants would provide more flexibility than a single Oracle-only base.
