LGTM! 🚀

We should probably look to see if we can auto update this dependency. We pinned because a new version broke it (obviously), so we don't want to just always do latest. But if we have auto-updating, then we wouldn't run into either issue again; new version would get PR and our check catalog-info.yaml workflow would be able to catch if new version has regression.

Not the easiest since the version is just in a run step.
