Description of problem:
During the upgrade of RHV Manager, we wanted to enable rhceph-4-tools-for-rhel-8-x86_64-rpms as a pre-requirement. As we enable repositories using Ansible Automation, we discovered an issue that Ansible reports there are more than one repository with the same name.

Version-Release number of selected component (if applicable):
rhceph-4-tools-for-rhel-8-x86_64-rpms
RH Satellite v6.9.6
Ansible 2.9

How reproducible:
Write an Ansible playbook and run it against to invetory.

Steps to Reproduce:
1. Add a task with loop like
```
  - name: Enable 8 repositories
    theforeman.foreman.repository_set:
      username: "{{ rhs_satellite_admin }}"
      password: "{{ rhs_satellite_admin_password }}"
      server_url: "{{ rhs_satellite_server_url }}"
      validate_certs: "{{ rhs_validate_certs }}"
      organization: "{{ rhs_org }}"
      label: "{{ item.label }}"
      repositories:
        - releasever: "{{ item.rel | default(omit) }}"
      state: "{{ item.state | default('enabled') }}"
    loop: "{{ rhs_repos_repolist }}"

```
2. Add inventory to the list like

```
rhs_repos_repolist:
  - label: "jb-eap-7.4-for-rhel-8-x86_64-rpms"
  - label: "ansible-2.9-for-rhel-8-x86_64-rpms"
  - label: "fast-datapath-for-rhel-8-x86_64-rpms"
  - label: "advanced-virt-for-rhel-8-x86_64-rpms"
  - label: "satellite-tools-6.9-for-rhel-8-x86_64-rpms"
  - label: "rhv-4-mgmt-agent-for-rhel-8-x86_64-rpms"
  - label: "rhvh-4-for-rhel-8-x86_64-rpms"
  - label: "rhv-4.4-manager-for-rhel-8-x86_64-rpms"
  - label: "rhceph-4-tools-for-rhel-8-x86_64-rpms"
```
3. Add credentials and variables to use from the task 1.

4. Run playbook to enable

```
Actual results:
