Code Review

This pull request adds a new model configuration, Qwen3-30B-A3B-NVFP4, to the Blackwell lm-eval test suite. The changes include adding the model's YAML configuration file, updating the list of models for the test, and increasing the CI job timeout to accommodate the new model. The changes are straightforward and appropriate for the stated purpose. I have one minor suggestion for consistency.
