hopefully the right place to ask. Is it possible to configure default credentials for registries like docker.io? we're now often hitting the new dockerhub pull limits, and were hoping to use the Registries config section in Harvester cluster mgmt through Rancher to add credentials with higher pull limits in the short term, before getting mirrors deployed. We know this should be the rke2 config passthrough, but we're not having luck adding credentials this way. We've verified that manually adding the credentials to the deployed workloads does work, but using those same credentials via the registries config does not.
