* Update test_qwen3_grpo.py to correct function call
This test file uses the incorrect name for the function, which is gradient_checkpointing_disable(), not disable_gradient_checkpointing().
I copied the line from test_llama32_sft.py - I'm not sure if this actually is required, just wanted it consistent for when other people like me test this and have no clue what they're doing when it throws an exception.
* Update blackwell/test_qwen3_grpo.py

1. Removed the `--extra-index-url https://wheels.vllm.ai/nightly` from the uv install instructions because this causes it to crash; Removing that flag solves the issue and is more stable overall. Tested with RTX 5090 CUDA 12.8 on Linux.
2. Removed `uv pip install -U triton>=3.3.1` because triton 3.3.1 is already installed with the vllm command.
