authorized_key: Allow local path to a key

SUMMARY

Add option to specify an absolute path to file with SSH key(s) for authorized_key

ISSUE TYPE

Feature Pull Request

COMPONENT NAME

authorized_key

ADDITIONAL INFORMATION


Before this change you would need to get key using ansible.builtin.slurp or something like ansible.builtin.command: cat <file> with register
I tried to keep it as simple as possible

# Now this is possible
- name: Set authorized keys taken from path
  ansible.posix.authorized_key:
    user: charlie
    state: present
    key: /home/charlie/.ssh/id_rsa.pub
