1.23.0

(fix): Endpoints whose request body is a referenced type no longer serialize path parameters into the JSON body. With respectOptionalRequestBody, an omitted optional body on such an endpoint now sends no body and no Content-Type instead of a body containing the path parameters.

(feat): Add the respectOptionalRequestBody configuration option. When enabled, an endpoint whose request body the API does not require lets callers omit the body: the request then carries neither a body nor a Content-Type header, instead of sending {} as application/json. Disabled by default.
