Thanks @Michaelvll! Has the updated image been pushed to our GCR repo? If yes, is. there a corresponding PR on skypilot-catalog repo to update images.csv? If not, that's okay, we can batch these changes in the next image push we do.

We have not pushed to the GCR repo yet. Good catch for the update of images.csv. Let's batch it for the next updated. : )
