What would you like to be added:

Errors handled in CheckErr function are unable to be elegantly handled if they are wrapped.

https://github.com/kubernetes/kubectl/blob/18a5313a74f7d83f6b54377d72b421b5ebfa66c9/pkg/cmd/util/helpers.go#L152

In the following code, the apierrors.isInvalid checks the error with errors.As which can process the error chain but the type conversion below err.(*apierrors.StatusError) could lead to bad type conversion when encountering wrapped errors.

	case apierrors.IsInvalid(err):
		details := err.(*apierrors.StatusError).Status().Details
		s := "The request is invalid"
		if details == nil {
			handleErr(s, DefaultErrorExitCode)
			return
		}

Why is this needed:

I'm not sure if kubectl library should be able to handle the wrapped errors. We want to reuse the CheckErr function from kubectl in other projects where errors can be wrapped. This can be fixed by converting err into APIStatus first and then extract the Details. If this enhancement is permitted, I would be willing to make a PR for it.

NOTE: formatting errors since go version 1.13 should be handled with %w: https://stackoverflow.com/questions/61283248/format-errors-in-go-s-v-or-w
