Passing db_name param to the describeCollection()

[rashgaroth]

Description

I've got an error when search with the specific db name, the error is : Cannot read properties of undefined (reading nq), that's because the code Data.ts does not passing the db_name parameter

Summary

This pull request to milvus/grpc/Data.ts includes changes to improve the handling of collection requests in the search method. The most important changes include importing the DescribeCollectionReq type and modifying the search method to use a default collection request.

Improvements to collection request handling:

• milvus/grpc/Data.ts: Added the DescribeCollectionReq import to support type checking for collection requests.
• milvus/grpc/Data.ts: Modified the search method to use a default describeCollectionRequest object and conditionally add the db_name if present in the request.
