[gnome-documents] Use pan-down-symbolic, not go-down-symbolic, in OverviewSearchbar

    Use pan-down-symbolic, not go-down-symbolic, in OverviewSearchbar
    
    ... because it opens a dropdown menu. The other one is for jumping to
    the next occurrence in a search.
    
    Original patch from Debarshi Ray for gnome-photos.
