[BUG] - overrideConfig not passed to Langsmith

[blackge]

Describe the bug When using overrideConfig to set tags and metadata in LangSmith, it is not passing the data through to langsmith.

To Reproduce Steps to reproduce the behavior:

When calling prediction API, set overrideConfig

overrideConfig: {
      "analytics": {
        "langSmith": {
          "tags": ["DEI"],
          "metadata": {
            "sessionId": sessionId ? sessionId : "123",
          }
        }
      }
    }

Expected behavior Metadata should appear in Langsmith

Screenshots Metadata does not appear.

Setup

• Installation on Railway
• Flowise Version 1.6.5
• OS: [e.g. macOS, Windows, Linux]
• Browser [e.g. chrome, safari]

Additional context This is possibly a documentation issue and an example is needed. However looking at the code in /packages/src/components/handler.ts the additionalHandlers isn't passing the options into the langSmith trace. Assuming options is what is passed in from the overrideConfig, this would explain why it doesn't get passed through. The same issue applies to the Langfuse call.
