The above description, with three-dash lines interspersed, looks
somewhat confused, but the contents of the patch matches the title.
Both upload and download are updated.

Curiously we have updated download side less than a month ago with
d014fb29 (build(deps): bump actions/download-artifact from 4 to 5,
2025-10-16).

Let's merge it down before the final.  Thanks.
