Issue: [BUG] PreTrainedTokenizerFast._batch_encode_plus() got multiple values for keyword argument 'truncation_strategy
Root cause: Interface Contract Mismatch

## Describe the bug
While running pipeline:
```bash
You cannot select the number of dataset splits for a generative evaluation at the moment. Automatically inferring.

## To Reproduce

```py
import sys
import os

sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))

from lighteval.logging.evaluation_tracker import EvaluationTracker
from lighteval.models.vllm.vllm_model import VLLMModelConfig
from lighteval.pipeline import ParallelismManager, Pipeline, PipelineParameters
from lighteval.utils.imports import is_accelerate_available

if is_accelerate_available():
    from datetime import timedelta
    from accelerate import Accelerator, InitProcessGroupKwargs

    accelerator = Accelerator(kwargs_handlers=[InitProcessGroupKwargs(timeout=timedelta(seconds=3000))])
else:
    accelerator = None


def evaluate():
    evaluation_tracker = EvaluationTracker(
        output_dir="./results",
        save_details=True,
        push_to_hub=True,
        hub_results_org="yujonglee",
    )

    pipeline_params = PipelineParameters(
        launcher_type=ParallelismManager.ACCELERATE,
        custom_tasks_directory="tasks",
        max_samples=10,
    )

    model_config = VLLMModelConfig(
        model_name="Qwen/Qwen3-0.6B",
        dtype="float16",
    )

    # https://huggingface.co/docs/lighteval/en/available-tasks
    tasks = ["helm|legal_summarization:billsum|0|0"]
    task = ",".join(tasks)

    pipeline = Pipeline(
        tasks=task,
        pipeline_parameters=pipeline_params,
        evaluation_tracker=evaluation_tracker,
        model_config=model_config,
    )

    pipeline.evaluate()
    pipeline.save_and_push_results()
    pipeline.show_results()


if __name__ == "__main__":
    evaluate()

```

## Expected behavior


Run without error.

Hi! I think it will be solved by @NathanHB 's PR #939
