Disable dependency gathering for release notes

Right now the collection of the dependencies is broken for the v1.26.0
tag, because we missed vendoring the following bits:

```
k8s.io/dynamic-resource-allocation => k8s.io/kubernetes/staging/src/k8s.io/dynamic-resource-allocation
k8s.io/kms => k8s.io/kubernetes/staging/src/k8s.io/kms
```

For now we disable the dependency collection to unbreak the `release`
GitHub action workflow.
