[NEW] Add valkey to docker-library official-images

[aas47]

The problem/use-case that the feature addresses

Valkey images not available under official docker images.
Valkey images not available on ECR.

Description of the feature

By adding valkey image to https://github.com/docker-library/official-images, the image will also be available via https://hub.docker.com/_/valkey.
This additionally I believe will make them available on ECR. This allows us to get around Docker Hub rate limit and pull the official image from ECR.

Alternatives you've considered

Just use docker pull docker.io/valkey/valkey for pulling the image.

Please let me know if this issue should be created under valkey-container repo.

I think it's fine to do it here. We haven't really considered it recently because it's usually a very high bar to achieve. Would you be willing to help get it started by creating the issue according to https://docs.docker.com/docker-hub/repos/manage/trusted-content/official-images/#:~:text=new%20Official%20Image.-,Creating%20a%20Docker%20Official%20Image,Documentation%20for%20Docker%20Official%20Images ?
