Update curl to Test Workflow Example

[za01br]

While following this workflow example The user will get the wrong output for "doubledValue" and "incrementedValue".

{ "triggerData":{ "triggerData":{ "inputValue":45 } }, "results":{ "stepOne":{ "status":"success", "output":{ "doubledValue":null } }, "stepTwo":{ "status":"success", "output":{ "incrementedValue":null } } }, "runId":"edfe93b1-ab09-418a-83ae-bf2cef96ccd2" }

This fix the input passed via the API call.
