[serge] Fix 2 integration tests for model helium failing with output_mismatch (list output differs (2))

[sergereview]

Original CI failure

• Failure group: 1/1: 2 integration tests for model heliumfailing withoutput_mismatch (list output differs (2))
• tests/models/helium/test_modeling_helium.py::HeliumIntegrationTest::test_model_2b [multi-gpu] (output_mismatch, seen 7/7)

Relates to #47538

The Helium test_model_2b integration test fails on CUDA because the device-specific expected generated text is stale. The model now produces the same text as the default expectation (...now and I have), while the CUDA 8 entry still expects the old text (...now, and I).

This is a test-expectation mismatch only; there is no model crash or numerical error. The patch updates the CUDA expectation to the current model output, matching the default expectation already in the file.

✅ Verified on GPU

serge ran the targeted @slow test(s) on a GPU runner and opened this PR only after they passed with this patch.
