Description

When the openAPI spec contains array types, the generator doesn't create proper Cwiki.

Example (incorrect) output:
...
|| Response Type | array[ErrorResult] |
|| Response Model | [array[ErrorResult] Model|#array[ErrorResult]ModelAnchor|Jump to model] |

It should be more like:
...
|| Response Type | array of ErrorResult |
|| Response Model | [ErrorResult Model|#ErrorResultModelAnchor|Jump to model] |

The mustache file looks correct, but it's using a field ({{{dataType}}} that puts in the square brackets, confusing Confluence. Simple escaping doesn't seem to work.

Start with the cwiki generator's Mustache template and run the reported openapi-generator command against the supplied declaration. Compare how array response types populate dataType and the generated Confluence links. Done means array responses render as “array of ErrorResult” and link to the ErrorResult model without array brackets in the anchor.
