ipadnsforwardzone: : 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

- `module` tag needs to be correct
- `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`
- `default` tag needs to match `argument_spec`
- `authors` needs to be given with the github user also: `Name (@user)`
- `action` parameter is missing and added

argument_spec

- `elements="str"` needs to be added to all list of string parameters

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