clocks/world: search for "Reykjav" not "Reykjavik"
    
    The city is called Reykjavík (note the í). Previously our search
    worked because the search function also looked in the name of the
    timezone, and the *timezone* name is "Atlantic/Reykjavik" - i.e.
    it's really Latin-ized in the name of the timezone. However,
    upstream intentionally stopped including the timezone name in
    search matches:
    https://gitlab.gnome.org/GNOME/gnome-clocks/-/merge_requests/199
    so that doesn't work any more. Just searching for "Reykjav"
    should solve the problem.
