No empty arrays in "required" field in Schema Object

[road21]

According to validation in https://github.com/OAI/OpenAPI-Specification/blob/master/schemas/v3.0/schema.json

"required": {
          "type": "array",
          "items": {
            "type": "string"
          },
          "minItems": 1,
          "uniqueItems": true
        }

Could it be just

"required" -> required.value.toNev.fold(Json.Null)(_.asJson)

?

Yep, since we already are putting nulls for Skippable values.
