Alerting: Add image url or file attachment to email notifications. (#49381)

Browse Source 
If an image token is present in an alert instance, the email notifier will attempt to find a public URL for the image token. If found, it will add that to the email as the `ImageLink` field. If only local file data is available, the notifier will attach the file to the outgoing email using the `EmbeddedImage` field.
