[serge] Fix 8 integration tests for model hunyuan_vl failing with output_mismatch (list output differs (8))

[sergereview]

Original CI failure

• Failure group: 1/1: 8 integration tests for model hunyuan_vlfailing withoutput_mismatch (list output differs (8))
• tests/models/hunyuan_vl/test_modeling_hunyuan_vl.py::HunYuanVLForConditionalGenerationIntegrationTest::test_small_model_integration_test_batch [multi-gpu] (output_mismatch, seen 7/7)

Relates to #47538

Updates stale expected generation strings in the hunyuan_vl integration tests. The failures are all output_mismatch assertions with no crash or shape error, indicating the hardcoded expectations drifted. The patch refreshes the expected decoded texts in the four failing batched/nested tests to match the current model outputs, while leaving the still-passing single-image expectations untouched.

✅ Verified on GPU
