Add methods to handle activity run asynchronously flag

New methods have been added to handle the custom property 'runAsynchronously' on a JsonObject activity. These methods will help in getting and setting a value that indicates whether a specified activity can trigger a workflow asynchronously. This additional level of control can enhance workflow execution based on specific requirements.
