Fix Webhook failures in k8s 1.22+

[Samze]

What this PR does / why we need it

Kubernetes 1.22 added a new subresource field kubernetes/kubernetes#100970. The knative pkg which is used the webhook had an issue that was resolved here knative/serving#11448.

This change bumps the knative pkg dependency which includes the fix but keeps it pinned on the 0.22 release branch.

In addition it adds 1.22.5 to the k8s testing matrix in Github actions.

fixes #214

Describe testing done for PR

1. Created k8s 1.22/1.23 on Kind
2. ko apply -f config/ with this change.
3. k apply -f samples/spring-pet-clinic
4. Verified the binding is successful.

Note

This bumps the knative pkg only two commits https://github.com/knative/pkg/commits/release-0.22 so should be a relatively low risk change.

Yes, the updated knative.dev/pkg@release-0.22 fixed the issue. Curious why is it pinned to an older version? Maybe worth testing with the latest knative.dev/pkg@release-1.2. I will update my sandbox with the latest and try using the samples.

I just verified knative.dev/pkg@release-1.2 has breaking changes. So the latest patch from knative.dev/pkg@release-0.22 is sufficient for now.
