Track Template Changes

You can now track template changes in an effective way with these enhancements:

1. The template_created webhook triggers on template creation.
2. The template_updated webhook triggers on these changes to a template:
   1. A role added or deleted.
   2. Template renamed.
   3. A section added to a content bundle.
      See the full webhook events list: Webhook Payload.
3. An optional fields=content_date_modified query parameter for List Templates shows the timestamp for the latest change to template content.
