Related to #49398 Bump Go module references from pkg/v2 and milvus-proto/go-api/v2 to pkg/v3 and milvus-proto/go-api/v3 so the client tracks the Milvus 3.x release line. This prepares the repository for the upcoming 3.x.y release by aligning imports, module dependencies, and proto API references with the new major-version module paths. --------- Signed-off-by: Congqi Xia <congqi.xia@zilliz.com>
