Fix dataset.save_to_disk(output_file) does not accept pathlib.Path object

[thaiminhpv]

When I follow this to run make_datasets.create_text_dataset and output to disk, then I got this error.
This PR is to fix that

Commands

 python -m swebench.inference.make_datasets.create_text_dataset \
    --dataset_name_or_path ./custom_hugging_face_dataset \
    --output_dir ./base_datasets --prompt_style style-3 \
    --file_source oracle \
    --splits test
