docs(angular/guides/testing): use 'provideHttpClientTesting' instead of the deprecated 'HttpClientTestingModule' and add 'initialPageParam' to the infinite query example

[sukvvon]

🎯 Changes

• The HttpClient section registered the deprecated HttpClientTestingModule. Provide provideHttpClient() and provideHttpClientTesting() instead, and update the text and the checklist item to match.
• The infinite query example defaulted pageParam in the queryFn signature, which v5 replaced with the required initialPageParam. Add initialPageParam: 1 and read pageParam directly.
