spec, status: Add architecture

The argument here is twofold:

- We used to show it with ostree refs because ostree doesn't have manifest lists,
  and people may have gotten used to seeing it in e.g. bug reports
- Highlight that the digest of the image is always
  the digest of the per-arch image; we currently peel and discard manifest
  lists, which may not be obvious.

Closes: #1238
