fix: pin google-genai < 2.0.0 in Gemini agent templates (#1433)

google-genai 2.0.0+ introduced breaking API changes (vertexai→enterprise
rename, new Interactions API structure). Fresh deploys on June 1 started
resolving to google-genai 2.7.0 via unpinned transitive dependencies,
causing runtime 500 errors on all Gemini-based e2e tests.

Pin google-genai to < 2.0.0 across all GoogleADK and LangGraph Gemini
templates to prevent the incompatible major version from being installed.
