trigger template image does not restore state

[Mariusthvdb]

The problem

as title (and opposed to the other trigger template platforms)

when using below trigger to create the template image, the dashboard shows a broken placeholder when HA starts, or template integration is reloaded

(we can add some extra triggers for those events, but that updates the template entity, and makes the picture-entity card show a dat of the last trigger, and not the date/time of the last snapshot creation)

What version of Home Assistant Core has the issue?

2023.7.1

What was the last working version of Home Assistant Core?
