While trying the version 1.1.0 of the Ansible Collection, we ran into the following issue:

It seems that the argument user_dn isn't handled in the system_access_users module.

To Reproduce
Steps to reproduce the behavior:

1. Create Playbook entry like:

- name: Get api key
  puzzle.opnsense.system_access_users:
    username: example_user
    password: "{{ ansible_password }}"
    apikeys: ""
  register: root_api_keys

2. run play against an OPNsense Instance
3. see error as described above

Expected behavior
The argument user_dn and other unkown arguments are expected and handled by the system_access_users module.
