* Re-run release notes tool

This time I deleted the release notes draft file before re-running the
tool with the same arguments as before.

* Re-run with the KIND changes

I went to my checkout of `kubernetes/release` and rolled it back like so:

```
git checkout 7ab229a48e00d8287ec1810b589a07c383b5913a
GO111MODULE=on go install k8s.io/release/cmd/release-notes
```
