CI: Fix release action for download-artifacts@v5 behavior

In v5 of the download-artifacts action, they made behavior more
consistent with regards to the resulting path when downloading a single
artifact. Unfortunately, this breaks our release action when it comes to
assembling all built packages into a single directory.

On the plus side, the current version of download-artifacts has the
requisite config to allow us to configure the action to extract all
artifacts into a single directory, ready for staging.
