Remove 'beta' from default storage class annotation

I forgot to update default storage class annotation in my storage.k8s.io/v1beta1 -> v1 PRs. Let's fix it before 1.6 is released.

I consider it as a bugfix, in #40088 I already updated the release notes to include non-beta annotation  `storageclass.kubernetes.io/is-default-class`

```release-note
NONE
```
