This commit addresses dependency injection defects when using the `withFetch` API. Formerly, utilizing `withFetch` led to the automatic setting of `HttpBackend` to `FetchBackend`, which proved problematic in certain scenarios. Notably, conflicts arose when integrating `withRequestsMadeViaParent` and manually overriding tokens, as observed in instances like `InMemoryWebApiModule`. PR Close #55652
