Dataset Viewer issue for claritylab/UTCD

### Description

The dataset viewer is not working for dataset claritylab/UTCD.

Error details:

```
Error code:   TooManyColumnsError

```


I'm having trouble to get dataset viewer to work. 

I did a bit of research:
- https://discuss.huggingface.co/t/the-dataset-preview-has-been-disabled-on-this-dataset/21339/3
- https://discuss.huggingface.co/t/dataset-preview-not-showing-for-uploaded-datasetdict/12603/4

and looks like the only way to get data viewer to work is to call `push_to_hub` s.t. there are `.parquet` versions of my dataset in the `ref/convert/parquet` branch. 

But I already had my dataset loading script with `json` in-place. I think I can both 1) keep the existing dataset loading script, and 2) add the `parquet` version of my datasets to the branch, as I think [`squad_v2`](https://huggingface.co/datasets/squad_v2/tree/main) is an example for that. 

So I created a branch and pushed my dataset again via python: 
```python
from huggingface_hub import create_branch
create_branch('claritylab/utcd', repo_type='dataset', branch='ref/convert/parquet')

dataset = load_dataset('claritylab/utcd', name='in-domain')
dataset.push_to_hub('claritylab/utcd', branch='ref/convert/parquet')
```

the code executed fine with no error and the output message below:
