No Version in Bazel Central Registry

Hello,

if i add the rules_buildx in version 0.0.1 into my MODULE.bazel no version can be found!

Another Problem that i have, i have used bildx.bzl from rules_oci/examples/dockerfile but i always get the error "no builder "builder-docker" found".

Is this a known problem or does i make something wrong?

Thanks a lot.
