Build for epel 9

[jw3]

Adds epel 9 builds in CI and for local containers.

The recipe here is a mix between the Fedora and epel 8 builds. There are quite a few missing epel components yet, they are being requested as part of #775. Eventually epel 9 will closely resemble the FC build and the specs should be merged. However for now we will maintain a separate spec like is done for epel 8.

This also adds a version suffix to the release artifacts. The intent is to guard against human error when manually moving artifacts between GitHub and Fedora releases.
