Automatically promote cri-tools / cni plugins releases

We run the following manual promotion command for each release of the CNI plugins as well as cri-tools by using [kpromo](https://github.com/kubernetes-sigs/promo-tools/tree/main/cmd/kpromo):

```
> go install sigs.k8s.io/promo-tools/v3/cmd/kpromo@latest
> kpromo gh --org kubernetes-sigs --repo cri-tools --bucket k8s-artifacts-cri-tools --release-dir release --tags v1.25.0
```

or

```
> kpromo gh --org containernetworking --repo plugins --bucket k8s-artifacts-cni --release-dir release --tags v1.1.1
```

The question is, can we automate this away by using a periodic prow job?

Alternatives:
- Promote the artifacts directly via GitHub actions from the corresponding projects (requires auth to be setup correctly)
- Wait for https://github.com/kubernetes/sig-release/issues/1372

cc @kubernetes/release-managers

Start by reading the kpromo gh command under promo-tools/cmd/kpromo and running the two documented promotion commands for cri-tools and CNI plugins. Determine how a periodic Prow job can invoke them and authenticate to the artifact buckets. Done means releases from both projects are promoted automatically without the current manual commands.
