Currently available images are: https://github.com/GoogleContainerTools/distroless#what-images-are-available

That is, maybe we should use gcr.io/distroless/static-debian11 directly instead of gcr.io/distroless/static. I think static is a link to the latest build static-debian11, but we should use the latest build explicitly, so that we have a reproducible build and so we don't auto-upgrade images when the static link changes.
