that the documentation section and the agument spec is complete. Needed
changes:

- `type: str` needs to be set for string parameters
- `type: int` needs to be set for integer parameters
- `type: list` needs to be set for list parameters
- `elements: str` needs to be given for list of string parameters
- `aliases` tag need to be consistent to `argument_spec`
- `authors` needs to be given with the github user also: `Name (@user)`

argument_spec

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

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