Updated the npu-smi command to retrieve version information more broadly and modified version parsing logic. Previous method need higher permission (sudo), causing error in cloud server sometimes .
Because `override_model_config` in **fsdp_workers.py** changes the model’s `attn_implementation` to **Flash Attention**, which is not currently supported on **Ascend**, the NPU must use **SDPA** or **eager attention** here instead.

Code Review
This pull request fixes a bug in device detection for Ascend NPUs and updates a launch command in the documentation. The change to verl/utils/device.py makes the npu-smi command more general, which is a good improvement for compatibility. However, the logic for parsing the software version has become fragile. I've provided a suggestion to make the version parsing more robust using a regular expression to prevent potential issues with incorrect version detection.
