When configuring a notification channel for STO exceptions using a webhook, there is currently no option to select or configure a custom Notification Template

Impact:

Because the payload cannot be customized, notifications sent to platforms like Google Chat via webhook are not recognized correctly. Unlike Pipeline notifications—which allow for custom templates to structure the JSON payload—STO exception notifications send a default payload that may be incompatible with specific third-party webhook requirements.

Use Case:

Users want to notify Google Chat rooms when an STO exception is created. Without template support, they cannot format the webhook payload to meet Google Chat's message schema, rendering the integration unusable.

Proposed Solution:

Expose the "Notification Template" configuration for STO exception notification channels (specifically for Webhook types) to provide parity with existing Pipeline notification functionality.
