Fix of #355 - deleting a collection

[Tompage1994]

Fixed an issue where if version was not specified in ah_collection and state=absent then the module will fail

What does this PR do?

How should this be tested?

CI has been updated (not that it will run at the moment)

Manually:

• create a collection in AH
• Set vars as follows:

  my_collection:
    name: galaxy
    namespace: galaxy
    path: galaxy-galaxy-1.1.1-devel.tar.gz

• run the following snippet

- name: Delete published collections
      infra.ah_configuration.ah_collection:
        name: "{{ my_collection.name }}"
        namespace: "{{ my_collection.namespace }}"
        state: absent
        ah_hostname: "{{ ah_hostname }}"
        ah_username: "{{ ah_username }}"
        ah_password: "{{ ah_password }}"
        ah_verify_ssl: "{{ ah_validate_certs }}"
