The attached patch to maintenance.git fixes the remaining minor issue:
Now Accept-Language language codes get normalized, zh to zh-CN, so web
browsers requesting any kind of Chinese get the website in mainland
Chinese.  (This is a minor issue.  The only valid URL is /zh-CN/ since
my last patch to guix-artwork because I don’t know how to
rewrite/redirect URLs in nginx.)

The patch was tested on a berlin VM.

There is no copyright header in maintenance.git’s
hydra/nginx/berlin.scm so I did not add a copyright.  I hereby license
the patch CC0

Shall I just push?  A reconfigure of berlin will be necessary but is
not urgent.

Regards,
Florian
