How to test it?

There's no unit tests, so i manually tested it by replacing the contents of node_modules/strapi-plugin-documentation/services/Documentation.js with the changes in this PR, then re-generated the API and now the API docs are showing the correct response:

responses": {
    "200": {
    "description": "Retrieve aaa-aa document(s)",
    "content": {
        "application/json": {
            "schema": {
                "type": "array",
                "items": {
                    "$ref": "#/components/schemas/Aaa-aa"
                }
            }
        }
    }
},
