• [X] I had searched in the issues and found no similar feature requirement.

Description

Current Situation: Typically, different knowledge bases have different requirements for the recall parameters. Currently, the configuration interface for the knowledge base only includes the recall parameters for the Embedding model and lacks the parameter settings for the reranker model.

Expectation: Add reranker model parameter settings, such as model name and topK parameter, to the knowledge base configuration interface.

现状：通常情况下，不同知识库对召回的参数有不同的要求，目前知识库配置画面只有Embedding的召回参数设置，缺少reranker模型参数设置； 期望：在知识库画面，增加reranker模型的参数设置，如模型名字，topK参数等。
