fix(knowledge): 修正 getConnector 不返回 fileConnectorConfig 问题

- 移除 collection-get 命令中对 fileConnectorConfig 字段的输出
- 文档中补充说明 getConnector 不返回 storeType、regionId、bucketName 等字段
- 更新类型定义，去除 RagConnectorInfo 中的 fileConnectorConfig 字段
- 明确这些字段只在创建连接时请求体中传入，查询时不可读取

 ```
 
-> 如果是 `CUSTOM` 存储，额外显示 `ossRegion` 和 `ossBucket`（注意：实测 getConnector 响应可能不返回 fileConnectorConfig，storeType 显示为 `-`）。
-
 quiet 模式：输出集合 ID。
 
 json 模式：返回 API 原始响应。
 
 **注意事项**
 
-- 无特殊注意事项。
+- getConnector 不返回 `fileConnectorConfig`（`storeType`/`regionId`/`bucketName`），这些字段仅在创建时通过请求体传入，查询时不可读回。
