check_mode suppor

[Ofthestreet]

In borg-client.yml, running the playbook in check mode is not possible since sshkey is undefined in the following task

- name: client | put sshpubkey on the normal backupserver
  authorized_key:
    user: "{{ item.user }}"
 ->   key: "{{ sshkey.stdout }}"

I would suggest to add a check_mode: no when fetching the ssh-key in order to validate the usage of sshkey.stdout

- name: client | fetch ssh-key
  command: "cat {{ borgbackup_ssh_key }}.pub"
  register: sshkey
  changed_when: false
  -> check_mode: no
  tags:
    - skip_ansible_lint

Note : As I am not a old ansible coder feel free to indicate why this is not already the case

Check mode was never tested while implementing the role, so I'm not sure if this would be the only issue? I expect that anything with ssh keys involved will fail if the key is not generated, so it probably doesn't make sense to implement check mode then?
