Take the Go package artifacts out of the delivery parts for now, so the running builder builds them (issue 1966)

The running builder predates Go package artifacts ("refused kind: package of language go ... no build module
builds it"), so it can build neither the new builder, the grants module, the Go build module nor the checker:
each new part is needed before the others can be built or delivered. For the bootstrap of the registry
delivery, at the operator's word (19:4x, "do the temporary change"), the package artifacts leave the manifests of
the parts that run; the contracts and SDK modules, which run on no node, keep theirs. They come back in one change
once the new builder runs. Quick vs thorough: quick; the thorough fix is 47/G's tier order (issue 1921 note 80).
