Stop an MCP Events subscription.

Forward an MCP server's `events/unsubscribe` requests here. The
subscription's endpoint is deleted. Unsubscribing from a subscription that
doesn't exist succeeds, so this can be repeated.

  - `arguments` object: The filter arguments the subscription was made with, as given to `events/subscribe`. See [Stop a subscription](https://developers.openai.com/plugins/build/mcp-events#stop-a-subscription) in OpenAI's MCP Events docs.
  - `delivery` McpEventsUnsubscribeDeliveryIn, required
    - `mode` 'webhook', required
