Publish official docker image to Public registry

[yogeek]

In #136 an official container release has been announced.
But it is not easy to find where the corresponding docker image is located.

Is it there : us-central1-docker.pkg.dev/k8s-staging-images/aws-encryption-provider/aws-encryption-provider:latest ? (found in this job logs : https://storage.googleapis.com/kubernetes-ci-logs/logs/aws-encryption-provider-push-images/1965173683215405056/build-log.txt)
If it is, I did not manage to pull it

docker pull us-central1-docker.pkg.dev/k8s-staging-images/aws-encryption-provider/aws-encryption-provider:latest           
Error response from daemon: manifest for us-central1-docker.pkg.dev/k8s-staging-images/aws-encryption-provider/aws-encryption-provider:latest not found: manifest unknown: Failed to fetch "latest"

Is it meant to be pulled like this or did I miss something?

What would you like to be added:

Publishing official docker image in a public registry like https://gallery.ecr.aws/ (other AWS addons are already there)

Why is this needed:

Today, it is not easy to understand where the official image should be pulled from. Adding it in a public registry could help users to have a clear location to pull from.
