patch

Adds missing /catalog-graph route to <CatalogGraphPage/>.

To fix this problem for a recently created app please update your app/src/App.tsx

+ import { CatalogGraphPage } from '@backstage/plugin-catalog-graph';
  ... omitted ...
  </Route>
    <Route path="/settings" element={<UserSettingsPage />} />
+   <Route path="/catalog-graph" element={<CatalogGraphPage />} />
  </FlatRoutes>

This fix also exists in version 0.4.16, which is part of the v0.65.1 release of Backstage.
