!path twice instead of checking for !path

In this conditional statement inside the if block, it is checking for !path twice instead of checking for !path and !heading. So, the corrected line should be:

if (!path || !heading) {

   let listItem = null;
          if (!path || !path || heading) {
            // if current route item has no path and children treat it as an API sidebar heading
            listItem = (
              <SidebarRouteTree
                level={level + 1}
                isForceExpanded={isForceExpanded}
                routeTree={{title, routes}}
                breadcrumbs={[]}
              />
            );

定位 issue 中所示的 SidebarRouteTree 条件，并检查其周围的 route-tree 逻辑。当该条件检查路径缺失或标题缺失，且站点现有的 checks 均通过时，即表示完成。
