Milvus vector store: Pass databaseName in DeleteParam for non-default databases

When using a non-default database, MilvusVectorStore's doDelete method wasn't
passing the specified databaseName in DeleteParam, causing searches to fall back
to the default database where collections couldn't be found. Added explicit
databaseName parameter to fix this issue.

- Add databaseName to DeleteParam builder
- Upgrade milvus-sdk from 2.3.4 to 2.3.5
