Add RHEL 9

* Add RHEL 9

This change adds support for RHEL 9 by building packages in the CI build pipeline, running the end-to-end tests on an RHEL 9 agent, and building, signing, and publishing packages to packages.microsoft.com and our GitHub release pages.

I confirmed that the CI build produces RHEL 9 packages, that those packages can be installed on an RHEL 9 agent, and that all the end-to-end tests pass.
