Feature request: Add dataset_version to ArizeDatasetsClient.run_experiment

[jamesyin-ontra]

Other parts of the codebase allow the dataset_version parameter, but the ArizeDatasetsClient.run_experiment function does not.
In my usage I feel that it makes sense to add this parameter to the function, as the occasion does arise where we need to use different versions of the same dataset to run experiments and compare before/after.

datasets do have IDs, and there are multiple versions per dataset ID, and the rest of the stack—storage, API, and SDK—already models that distinction. The missing piece is just that run_experiment doesn’t expose the version
selector yet

Spoke with Kiko on this one, will be done in 2026
