fix(GraphRunner): replace path param with config in fromWorkflow method

A change has been made to the fromWorkflow method in the GraphRunner component. The path parameter has been deprecated in favor of using a 'config' parameter which is the yaml configuration of the workflow. This makes the process of configuring a workflow more streamlined.
