+(fix) Adds locationAnalyzer to default-app template
+
+The locationAnalyzer was missing from the default-app template.
+This resulted in 404 errors in newly bootstrapped backstage applications,
+when adding components without configuration.
+
+To fix this in an existing backstage application, the locationAnalyzer needs
+to be carried from the builder to the router in the
+`packages/backend/src/plugins/catalog.ts` file.
+
+```diff
+   const builder = new CatalogBuilder(env);
+   const {
+     entitiesCatalog,
+     locationsCatalog,
+     higherOrderOperation,
++    locationAnalyzer,
+   } = await builder.build();
+   // ...
+   return await createRouter({
+     entitiesCatalog,
+     locationsCatalog,
+     higherOrderOperation,
++    locationAnalyzer,
+     logger: env.logger,
+   });
+```
