Description of problem:
Ceph preflight for ceph6 fails with two problems:
1- Trying to disable repositories that don't exist (at least from my experience)
2- Tries to enable rhceph-7-tools-for-rhel-9-x86_64-rpms instead of rhceph-6-tools-for-rhel-9-x86_64-rpms, for a ceph 6.0 installation

Version-Release number of selected component (if applicable):

$ rpm -qa |grep  ansible
ansible-core-2.14.2-5.el9_2.x86_64
ansible-collection-community-general-4.0.0-1.1.el9ost.noarch
ansible-collection-ansible-posix-1.2.0-1.3.el9ost.noarch
cephadm-ansible-3.0.0-1.el9cp.noarch

$ sudo subscription-manager repos --list-enabled
+----------------------------------------------------------+
    Available Repositories in /etc/yum.repos.d/redhat.repo
+----------------------------------------------------------+
Repo ID:   rhel-9-for-x86_64-appstream-rpms
Repo Name: Red Hat Enterprise Linux 9 for x86_64 - AppStream (RPMs)
Repo URL:  https://cdn.redhat.com/content/dist/rhel9/$releasever/x86_64/appstream/os
Enabled:   1

Repo ID:   rhel-9-for-x86_64-baseos-rpms
Repo Name: Red Hat Enterprise Linux 9 for x86_64 - BaseOS (RPMs)
Repo URL:  https://cdn.redhat.com/content/dist/rhel9/$releasever/x86_64/baseos/os

Repo ID:   rhceph-6-tools-for-rhel-9-x86_64-rpms
Repo Name: Red Hat Ceph Storage Tools 6 for RHEL 9 x86_64 (RPMs)
Repo URL:  https://cdn.redhat.com/content/dist/layered/rhel9/x86_64/rhceph-tools/6/os
Enabled:   1

How reproducible:
Attempt ceph ansible preflight for ceph 6.0 on RHEL 9.2 host

Steps to Reproduce:
1. Enable repos above, install ceph-ansible, setup inventory and ensure all hosts are reachable
2. Run preflight with option:
cd /usr/share/cephadm-ansible
ansible-playbook  cephadm-preflight.yml --extra-vars "ceph_origin=rhcs"


Actual results:

Expected results:

Installation complete.

Additional info:

I can work around this by:

1- Commenting out the problematic repositories:

# cat ./cephadm-preflight.yml |grep -A 4 repos_to_disable
    repos_to_disable:
#      - rhceph-4-tools-for-rhel-{{ ansible_facts['distribution_major_version'] }}-{{ ansible_facts['architecture'] }}-rpms
#      - rhceph-4-mon-for-rhel-{{ ansible_facts['distribution_major_version'] }}-{{ ansible_facts['architecture'] }}-rpms
#      - rhceph-4-osd-for-rhel-{{ ansible_facts['distribution_major_version'] }}-{{ ansible_facts['architecture'] }}-rpms
      - rhceph-5-tools-for-rhel-{{ ansible_facts['distribution_major_version'] }}-{{ ansible_facts['architecture'] }}-rpms
--

2- I need to change ceph_rhcs_version from 7 to 6:

# cat ceph_defaults/defaults/main.yml |grep ceph_rhcs_version
ceph_rhcs_version: 6 # By default it seems to be 7
