Fix CD: Packages Service First (#12764)

* Fix CD: Packages Service First

Build the packages.spack.io service images first, so they are
guaranteed to be pushed even if further images fail to build.

Fix the query to the `spack` script executed in later builds.

* CD: Remove Spack Images

Now done on Dockerhub.
