handle future deprecation argument
getting this error:
```
/root/miniconda3/envs/py3.10/lib/python3.10/site-packages/datasets/table.py:1387: FutureWarning: promote has been superseded by mode='default'.
  return cls._concat_blocks(pa_tables_to_concat_vertically, axis=0)
```

Since datasets supports arrow greater than 8.0.0, we need to handle both cases.
