Replace rules are not inherited by consumers of buildx as a module, and as such would default to use the v0.26.2 version. Removing the replace rules also removes various (indirect) dependencies (although brings in some new packages from k8s itself). The "azure" and "gcp" authentication packages in k8s.io/go-client are now no longer functional, so removing those imports. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
