Describe the bug

Document is different with source of --reasoning-parser value。

In document, https://docs.sglang.ai/backend/separate_reasoning.html,

Currently, SGLang supports the following reasoning models:

[DeepSeek R1 series](https://huggingface.co/collections/deepseek-ai/deepseek-r1-678e1e131c0169c0bc89728d): The reasoning content is wrapped with <think> and </think> tags.

[QwQ](https://huggingface.co/Qwen/QwQ-32B): The reasoning content is wrapped with <think> and </think> tags.

In source code,

  --reasoning-parser {deepseek-r1,qwen3}
                        Specify the parser for reasoning models, supported parsers are: ['deepseek-r1', 'qwen3'].

execute below code will get the result,

python -m sglang.launch_server --help

Reproduction

python -m sglang.launch_server --help
