CI: Push docker images directly to registry (#16488)

Exporting docker images to disk and reimporting them in the next job is very expensive. It's more efficient to push them directly from the builder job to the registry. `dist_docs` implicitly pulls the image from the registry.

Updates `distribution-scripts` dependency to crystal-lang/distribution-scripts@d1d8657

This includes the following changes:

* crystal-lang/distribution-scripts#395
