this is probably a silly question but will a trailing comma be okay? im guessing yes and that the effort to remove it isn't worth it XD

Yeah I think so - this is taken verbatim from chains own publish script: https:/tektoncd/chains/blob/main/release/publish.yaml

Comparing this to Chains publish task, we are missing REGION specific sha in the result here

https:/tektoncd/chains/blob/main/release/publish.yaml#L202

Do we need to add one more echo command here?

Edit: replaced L184 with L202 in the URL

I'd recommend adding that in so that all images are signed
