!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={[]}
              />
            );

Locate the SidebarRouteTree conditional shown in the issue and inspect its surrounding route-tree logic. Done means the condition checks for a missing path or missing heading, with the site's existing checks passing.
