go.mod: update k8s deps to v0.26.2 (remove "replace" rule)

Browse Source 
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.
