QA workflows don't accept debian:upload artifacts
From: https://salsa.debian.org/freexian-team/debusine/-/merge_requests/2445#note_697204
In the QA workflow and its children, we assume that we're dealing with `debian:binary-package` artifacts in many places. For example any architecture-handling code.
We document the workflows as accepting `debian:upload` artifacts, but we don't test for supporting these correctly, and in some(many?) cases we don't.
We could probably just resole this by restricting the input to `debian:binary-package` artifacts (and documenting that).
