Bump kind to v0.11.1

[croomes]

kube-proxy on clusters created with kind < v0.11.0 on linux 5.12.2 and later will fail to start, leading to the k8s network not becoming ready.

This was fixed in kubernetes-sigs/kind#2240. More details in that issue.

We're seeing this error on Github Actions pipelines but also on my desktop where I've confirmed bumping the kind dependency solves the issue.

Logs from kube-proxy:

go mod tidy produced more changes than I was expecting.

@croomes thank you so much for this! In the future we really appreciate if you sign you commits for DCO... in this case, in review the changes are from the community and are only dependency reference changes (and not contributions which could be questionable) and thus are fine. Really appreciate your help in making kuttl better!
