Make datasets.upsertRemoteExperiment API available in SDK

[msciortino]

Describe the feature or potential improvement

After creating a dataset, through the UI is possible to configure a remote experiment for the dataset as shown in
https://langfuse.com/docs/evaluation/experiments/experiments-via-sdk#optional-trigger-sdk-experiment-from-ui

This UI action calls the POST /api/trpc/datasets.upsertRemoteExperiment API providing as input:

{
  "json": {
    "projectId": <projectId>,
    "datasetId": <datasetId>,
    "url": <url>,
    "defaultPayload": <defaultPayload>
    }
 }

Issue

Langfuse SDK does not allow to call the updateDataset operation so we are not able to pre-configure the remote webhook url and payload for our AI engineers.

As we generate multiple datasets on the fly (hundreds), having to do this action manually for all of them is unfeasible.

Suggestions

1. Allow to set the remoteExperimentUrl and remoteExperimentPayload in create_dataset sdk method (preferred)
2. Add an update_dataset method to set remoteExperimentUrl and remoteExperimentPayload

I see. Thanks for sharing, this makes sense!
