Revert workaround related to RKE2 cisnetworkpolicy Node finalizer
Closes #1425 (closed)
It is now safe to remove the workaround, which was cleaning Nodes created with RKE2 before 1.28.9. The nodes created with Sylva 1.1.1 were created with the bogus finalizer, but since this policy is active in Sylva 1.1.1, we can remove it when we upgrade to Sylva 1.2.
This reverts !2549 (merged) (except that I kept some Kyverno RBAC things because after !2549 (merged) we introduced policy on Nodes and Machines).
