Fix script with old integration

Hi!

I used to have the Einkaufslisten integration in Home Assistant which I refreshed via a script. It seems like Einkaufsliste was discontinued so I removed it. However, now I get a warning stating "Einkaufsliste synchronisieren uses an unknown action“. When I click it and then the link to edit the automation I see an error „Only automations in automations.yaml are editable.“ I have no clue where this automation actually resides. Can you please help me finding it?
