Bumping the k8s.io dependencies to v0.26.7. The main intention
is to update the client-go library dependency for kube 1.27+,
where aggregated discovery is enabled. With client-go lower than
v0.26.4 in some cases it is possible that the discovery response
comes with the malformed response with nil GVK leading to Crash
Loop Back Off state.
