ChangeLoggedModel should inherit WebhooksMixin #11737
Description
Proposed Changes
Add WebhooksMixin to the list of superclasses from which ChangeLoggedModel inherits.
Justification
Every subclass of ChangeLoggedModel currently also inherit from WebhooksMixin, with two exceptions:
extras.Branchextras.StagedChange
This change will effectively enable webhooks for the two models above, which I believe is reasonable.
