Add a new hook workflow deactivate

The idea is:

Provide a hook ala workflow.activate but for deactivation.
Configuration - n8n Documentation

My use case:

embedded workflowengine. Applications needs to know which workflows are available.

I think it would be beneficial to add this because:

would help in embedded use cases, because a workflow must starts with ta request to a webhook.
If the workflow is not activated the webhook does not exist. So it make sense to inform the partner app, that the workflow was deactivated.

Any resources to support this?
