[Feature]: Qwen3-Rerank-8B online serving score API

[JiayuJeff]

🚀 The feature, motivation and pitch

The latest Qwen3-Rerank-8B model is not supported by accessing the online serving API.
When I run vllm serve Qwen/Qwen3-Reranker-8B --task score --port 7001, and request the score API service similar to https://github.com/vllm-project/vllm/blob/main/examples/online_serving/openai_cross_encoder_score.py, the error occurred is {'object': 'error', 'message': 'The model does not support Score API', 'type': 'BadRequestError', 'param': None, 'code': 400}.

Alternatives

Use HF implementation instead for now.

Similar to #19229 which is opened two weeks ago but still not supported.
