Cannot talk to SSL enabled Zabbix Server

SUMMARY

When configuring the new vars with a Zabbix server that uses HTTPS, the module complains that it's HTTP request is sent to an HTTPS server:

CONFIGURATION

n/a

OS / ENVIRONMENT / Zabbix Version

6.0 on Debian

STEPS TO REPRODUCE

Run the role with the settings below

###
# Zabbix agent configuration
###
zabbix_version: '6.0'
zabbix_agent_version: "{{ zabbix_version }}"
zabbix_server_version: "{{ zabbix_version }}"
zabbix_repo: 'zabbix'

zabbix_agent_server: 'monitoring.zm1.element-networks.nl
zabbix_agent_serveractive: "{{ zabbix_agent_server }}"

zabbix_api_server_host: 'monitoring.zm1.element-networks.nl'
zabbix_api_server_port: 443
zabbix_api_use_ssl: true
zabbix_api_login_user: 'zabbix-cli'
zabbix_api_validate_certs: true
zabbix_api_login_pass: !vault |
          $ANSIBLE_VAULT;1.1;AES256
          blabla

zabbix_api_create_hosts: true
zabbix_api_create_hostgroup: true
zabbix_agent_tlspsk_auto: true

zabbix_agent_link_templates:
  - 'Template OS Linux'

EXPECTED RESULTS

Not to break

ACTUAL RESULTS

See above, the error is quite clear

POSSIBLE FIX

Add ansible_httpapi_use_ssl to this task:

- name: "Run the API calls to Zabbix Server"
  vars:
    gather_facts: false
    ansible_user: "{{ zabbix_api_login_user }}"
    ansible_network_os: community.zabbix.zabbix
    ansible_connection: httpapi
    ansible_httpapi_use_ssl: "{{ zabbix_api_use_ssl }}"
    # Can't think of a way to make http_login_* vars be undefined -(
    http_login_user: "{{ zabbix_api_http_user | default(-42) }}"
    http_login_password: "{{ zabbix_api_http_password | default(-42) }}"
  include_tasks: api.yml
  when:
    - (zabbix_api_create_hostgroup | bool) or (zabbix_api_create_hosts | bool)
  tags:
    - api

However, this opens up a new 401 Unauthorized error when using HTTP Basic Auth... Which reminds me of #565

ansible-collections / community.zabbix
