Description of problem:
When attempting to create an image that uses an RHSM repo, like the rhel-9-for-x86_64-rt-rpms repo for kernel-re, Composer will always fail to start the compose with the error 'DNF error occurred: MarkingErrors: Error occurred when marking packages for installation: Problems in request: missing packages: kernel-rt'

Version-Release number of selected component (if applicable):
[jswanson@josh-edge-device ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux release 9.2 (Plow)

[jswanson@josh-edge-device ~]$ sudo dnf list installed | grep composer
cockpit-composer.noarch 45-1.el9_2 @rhel-9-for-x86_64-appstream-rpms

What's interesting is that composer will depsolve and appear to be ready to go:
[jswanson@josh-edge-device ~]$ sudo composer-cli blueprints depsolve rhde-rt-image
blueprint: rhde-rt-image v0.0.3
json-glib-1.6.6-1.el9.x86_64
libseccomp-2.5.2-2.el9.x86_64
<removedsomelines>

kernel-rt-5.14.0-284.11.1.rt14.296.el9_2.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Install using documented procedure
2. Add source
3. Create blueprint with customizations above
4. Attempt to compose image

Actual results:
Composer will always fail to start the compose with the error 'DNF error occurred: MarkingErrors: Error occurred when marking packages for installation: Problems in request: missing packages: kernel-rt'

Expected results:
Composer successfully composes an image
