Previously, ValidateNodeSelector did not check that labels are valid. Now it does for resource.k8s.io, regardless whether an object already was created with invalid labels in an earlier Kubernetes release. Theoretically this is a breaking change and could cause problems during an upgrade, but that is highly unlikely in practice. In contrast to node affinity, DRA does not ignore parse errors (= uses NewNodeSelector, not NewLazyErrorNodeSelector), so invalid labels would have been found instead of being silently ignored. Even if some object has invalid labels, this only affects an alpha -> beta upgrade which isn't guaranteed to work seamlessly.

What this PR does / why we need it
This PR updates the documentation for the
eviction-max-pod-grace-periodparameter to accurately reflect its current behavior. The existing documentation suggested that negative values would defer to the pod's specified grace period, but in practice, this is not the case.Changes made
Special notes for reviewers
The change is focused on aligning documentation with actual implementation behavior, as discussed in the original issue.
Fixes kubernetes#118172
