Guided Exercise: Install and Update Software Packages with DNF
Issue description
as observed by internal Red Hat user , Kazuo Moriwaka on service now ticket RHT2238618

"Description: Both of " dnf history undo " and " dnf history rollback " are not supported by Red Hat. Please add WARNING like product document:

Important
Downgrading RHEL system packages to an older version by using the dnf history undo and dnf history rollback command is not supported. This concerns especially the selinux, selinux-policy-*, kernel, and glibc packages, and dependencies of glibc such as gcc. Therefore, downgrading a system to a minor version (for example, from RHEL 9.1 to RHEL 9.0) is not recommended because it might leave the system in an incorrect state.
