Support for release Alpine aarch64 packages

[janario]

As reported at corretto/corretto-docker#46

It seems that no packages for Alpine(aarch64) are released. As I see a step to enable this would to include in the release process such step to publish the alpine package. Only then docker images would be possible.

Not sure in which project the release and publish is addressed but it seems to me that here would be a good start.

Is your feature request related to a problem?

During the release/publish process we would require a new step for publishing aarch64 for alpine https://apk.corretto.aws
