ipadnszone: Fix documentation sections and agument spec

ansible-test with ansible-2.14 is adding a lot of new tests to ensure
that the documentation section and the agument spec is complete. Needed
changes:

DOCUMENTATION section

- `type: str` needs to be set for string parameters
- `type: list` needs to be set for list parameters
- `elements: str` needs to be given for list of string parameters
- `suboptions` instead of `options` needs to be used for dict parameters
- `aliases` tag needs to match `argument_spec`
- `type` tag needs to match `argument_spec`
- `required` tags need to be fixed according to the `argument_spec`
- `authors` needs to be given with the github user also: `Name (@user)`

RETURN section

- `type: dict` needs to be given for dicts
- `contains` needs to be used instead of `options` for dicts
- `type: str` needs to be used for string parameters

argument_spec

- `elements="str"` needs to be added to all list of string parameters
- `elements="dict"` needs to be added to all list of dict parameters
- `type=str` and `type=int` need to be replaced by `type="str"` and
  `type="int"`

The `copyright` date is extended with `-2022`.
