Property requestBody should be of type String instead of RequestBody in Links.java (OAS 3.0)

Hi team,

In Links.java, property requestBody should be of type String instead of RequestBody as it's clearly mentioned as below in https://github.com/OAI/OpenAPI-Specification/blob/3.0.1/versions/3.0.1.md#linkObject

requestBody	Any | {expression}	A literal value or {expression} to use as a request body when calling the target operation.

Note: We used Map<String, String> for parameters field in Links.java

Thanks,
Mohammed
