Subject: [PATCH] Remove edge from approval to proceed and cancel

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.`
