Removed added edges from `approval_node` node to `proceed` and `cancel`. These edges are causing an error where the graph tries to update `status` channel at the same time (in node `proceed` and `cancel`) Also since we have `approval_node` already points to `proceed` and `cancel`, adding these edges is unnecessary. Error message if the example compiled without any changes: `InvalidUpdateError: At key 'status': Can receive only one value per step. Use an Annotated key to handle multiple values.`
