bug#53923: ‘http-fetch’ is unable to fetch <https://repology.org/api/v1/project/emacs:modus-themes>

[Xinglu Chen]

Hi,

For some reason, the ‘http-fetch’ procedure in (guix http-client) is
unable to fetch
<https://repology.org/api/v1/project/emacs:modus-themes>.

The URL opens just fine in Icecat.  ‘http-request’ from (web client) is
able to handle it as well.
