…tform v2 aiplatform v2's langchain extra moves langchain from 0.3 to 1.x, which relocates the legacy agent and chain APIs into the separate langchain-classic distribution that the extra now installs. Repoint the two Vertex sample templates at their new locations. Bump samples/langchain_on_vertexai/requirements.txt in lockstep. That file is passed to ReasoningEngine.create() and is what the deployed agent installs, so leaving it on v1 would resolve langchain 0.3 and fail to find langchain_classic at import time. Pin langchain-classic explicitly rather than relying on the extra to supply it. The extra's contents are exactly what shifted here -- v2 also dropped langchain-google-vertexai in favor of langchain-google-genai.

Description
Supersedes #438 (cross-repo, so it couldn't be used as a base or pushed to). Carries renovate's bump plus the fix it needs.
