Add retry mechanism to get_parquet_file in parquet metadata step
...to see if it helps with [FineWeb](https://huggingface.co/datasets/HuggingFaceFW/fineweb) `config-parquet-metadata` issue. 

Currently the error says just `Server disconnected` which seems to be a `aiohttp.ServerDisconnectedError` error.

If that works, a more fundamental solution would be to completely switch to `HfFyleSystem` instead of `HTTPFileSystem` and remove retries.
