ipatrust 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: int` needs to be set for integer parameters
- `type: bool` needs to be set for bool parameters
- `required` tags need to be fixed according to the `argument_spec`
- `default` tag needs to match `argument_spec`
- `author` needs to be given with the github user also: `Name (@user)`
- `choices` needs to match `argument_spec`

argument_spec

- `default=.*` needs to be dropped if `required=True` is also given

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