    gnu-maintenance: Produce mirror:// URIs in latest-html-release.
    
    Partially fixes <https://issues.guix.gnu.org/57477>.
    
    I'm not aware of a package using both latest-html-release and mirrors, so it
    has not been completely tested.  However, updating "yt-dlp" appears to work
    (except for git-fetch not being supported yet).  The expression for the
    signature-urls field had to be tweaked to not call uri-mirror-rewrite on 
#false.
    
    * guix/gnu-maintenance.scm 
(latest-html-release)[url->research]{urls,signature-urls}:
    Call uri-mirror-rewrite on the URLs.
