Documentation code examples in React Query's advanced SSR and Suspense guides are updated to use environmentManager.isServer() for server-vs-browser detection instead of a deprecated isServer flag. This change appears across six code snippets in two guide files.

Advanced SSR guide snippets `docs/framework/react/guides/advanced-ssr.md`	Three code snippet sections (`Providers` setup, `app/get-query-client.ts`, and experimental `ReactQueryStreamedHydration` provider) updated to import and branch on `environmentManager.isServer()` instead of `isServer`.
Suspense streaming guide snippet `docs/framework/react/guides/suspense.md`	Server streaming example code block updated to import `environmentManager` and branch on `environmentManager.isServer()` instead of the `isServer` flag.
