Thanks @vaikas! Can you rebase on https://github.com/tektoncd/chains/pull/613/files so we can pull both of these in?

(I suspect this change fixes the issues we were seeing in the other PR).

@wlynch sure thing. I poked around in pipelines since I recalled there was some work getting pipeline to work with 1.25 but couldn't figure out it the support was added, so left it out first :)
