Subject: [PATCH] Return the data type "string" for the enum PHP class in the
 JSON Schema document.

Actually, the JSON Schema document specifies the data type "object". According to my interpretation of the specification, it should be a string ( https://swagger.io/docs/specification/data-models/enums/ )
