DebDiff workflow creates DebDiff task with artifacts with "debian:binary-package" and "debian:upload"

See https://debusine.debian.net/debian/base/work-request/121244/

Error:

Failed to compute dynamic data: All binary artifacts must have the same category. Found "debian:binary-package" and "debian:upload"

IIRC and quick check: the DebDiffWorkflow was expected to introspect the debian:upload and use the related binary-package(s) (see DebDiffWorkflow._package_arch_pairs).

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
