[QUESTION]文档更新

### 请描述您的问题
这个文档是不是好久木有更新了哇？
https://github.com/alibaba/fastjson2/wiki/features_cn
我看源码里的好多配置在文档中都搜不到解释呢


Start with the linked wiki page, features_cn, and compare its documented configuration options with the configurations visible in the fastjson2 source. Identify which options lack explanations and confirm their current behavior before updating the documentation. Done means the relevant source configurations are covered clearly in the wiki.
