Epic Goal

Update our Jenkins images to be built on top of RHEL 9.

Why is this important?

RHEL 9 is the stable base OS for OCP 4.16. Keeping images up to date with RHEL ensures kernel-level compatibility and support for the latest bug/security fixes.

Out of scope - migrating to Konflux.

Scenarios

Acceptance Criteria (Mandatory)

• Jenkins uses UBI/RHEL9 as its base image.
