[gnome-shell] data: Rename custom close icon

[Marge Bot <marge-bot src gnome org>]

    data: Rename custom close icon
    
    Resource icons are added to the fallback icon theme, so they won't
    get used if a matching icon is found in the configured theme.
    
    That includes fallback names, so Adwaita's "window-close-symbolic"
    takes precedence over "window-close-24-symbolic" in hicolor.
    
    Fix this by using a custom name for a custom icon.
