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. Upstream kubernetes issue: https://github.com/kubernetes/kubernetes/pull/116603 Signed-off-by: karthik-us <ksubrahm@redhat.com>
