[rpm_key] Pass GPG key as string value

[infame-io]

SUMMARY

It would be great if the GPG key could be passed as a string value into the ansible.builtin.rpm_key module. This would allow passing the GPG key as an env. variable

export GPG_KEY="-----BEGIN PGP PUBLIC KEY BLOCK-----

mQGNBGUhLi4BDACrXw5kkEdclg7edHjzs3dCs4GIn7ct/tkyhi0Sw5cmH8txujPi
...

=NXmg
-----END PGP PUBLIC KEY BLOCK-----"

- name: Import GPG key
  hosts: sandwich

  tasks:
    - name: Import key (env. var)
      become: true
      ansible.builtin.rpm_key:
        key: '{{ lookup("env", "GPG_KEY" )}}'
        state: present

and it could enable passing the GPG key from services like AWS Systems Manager Parameter Store

one thing I missed, the key: option is missing an update, add 'since version 2.17 you can also pass the key as a string'
