osbuild now supports using the `--export` flag (can be invoked multiple times) to request the exporting of one or more artefacts. Omitting it causes the build job to export nothing. The Koji API doesn't support the new image types (yet) so it simply uses the "assembler" name, which is the final stage of the old (v1) Manifests.
