Update RELEASE.md (#8937)

If opening https://groups.google.com/g/kubernetes-dev we can see the
following message:

  As of January 2, 2022, this group will be sunset in favor of dev@kubernetes.io.

So this replaces kubernetes-dev@googlegroups.com with the new one.

In addition, this adds actual steps to know how to create container images easily.

## Container image creation
The container image `quay.io/kubespray/kubespray:vX.Y.Z` can be created from Dockerfile of the kubespray root directory:
```shell
cd kubespray/
nerdctl build -t quay.io/kubespray/kubespray:vX.Y.Z .
nerdctl push quay.io/kubespray/kubespray:vX.Y.Z
```
The container image `quay.io/kubespray/vagrant:vX.Y.Z` can be created from build.sh of test-infra/vagrant-docker/:
```shell
cd kubespray/test-infra/vagrant-docker/
./build vX.Y.Z
```
Please note that the above operation requires the permission to push container images into quay.io/kubespray/.
If you don't have the permission, please ask it on the #kubespray-dev channel.
