fix ReferencePolicyList.Items type

[dprotaso]

What type of PR is this?

What this PR does / why we need it:

When the ReferencePolicy type was added back the list type for that resource actually returns ReferenceGrants instead of ReferencePolicy. This isn't a huge deal but a lot of code generation around k8s types assume a pattern of XResource with a XResourceList having an Items type of []XResource

Which issue(s) this PR fixes:

N/A

Does this PR introduce a user-facing change?:

ReferencePolicyList Items is an array of ReferencePolicy again

Hi @dprotaso. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Weird - I thought I was a member of the k8s org - does the k8s-sigs have it's own org/membership repo?
