refresh: Update the source code URL. 

Reported by Tobias Geerinckx-Rice <me@tobias.gr>
in <https://bugs.gnu.org/35010>.

* guix/upstream.scm (update-package-source): Take 'source' instead of
'version' as the second argument.
[update-expression]: Change to take 'replacements', a list of
replacement pairs.
Compute OLD-URL and NEW-URL and replace the dirname of the OLD-URL with
that of NEW-URL.
* guix/scripts/refresh.scm (update-package): Adjust call to
'update-package-source' accordingly.
