tidb集群中的cdc添加新配置参数后，无法正常启动cdc组件，报错：component TiCDC server's config file conf/cdc.toml contained unknown configuration options: sorter.cache-size-in-mb, sorter.sorter-dir

你这个报错就是 cdc 不识别参数啊。

 tiup cdc version
Starting component cdc: /root/.tiup/components/cdc/v8.1.0/cdc version
Release Version: v8.1.0
Git Commit Hash: 137ed650cc3fcd04ed31b4e7978dccebc087330d

用类似语法，看下对应部署目录下 cdc 的版本呢。
