error when loading dataset in Hugging Face: NoneType error is not callable

### Describe the bug

I met an error when running a notebook provide by Hugging Face,  and met the error.

```

I have checked my internet, it worked well. And the dataset name was just copied from the Hugging Face. 
Totally no idea what is wrong! 

### Steps to reproduce the bug

To reproduce the bug you may run

```
from datasets import load_dataset, Dataset

# Load the enhancers dataset from the InstaDeep Hugging Face ressources
dataset_name = "enhancers_types"
train_dataset_enhancers = load_dataset(
        "InstaDeepAI/nucleotide_transformer_downstream_tasks_revised",
        dataset_name,
        split="train",
        streaming= False,
    )
test_dataset_enhancers = load_dataset(
        "InstaDeepAI/nucleotide_transformer_downstream_tasks_revised",
        dataset_name,
        split="test",
        streaming= False,
    )
```

### Expected behavior

1. what may be the reasons of the error
2. how can I fine which reason lead to the error
3. how can I save the problem

### Environment info

```
- `datasets` version: 3.2.0
- Platform: Linux-5.15.0-117-generic-x86_64-with-glibc2.31
- Python version: 3.9.21
- `huggingface_hub` version: 0.27.0
- PyArrow version: 18.1.0
- Pandas version: 2.2.3
- `fsspec` version: 2024.9.0
```

Hi ! I couldn't reproduce on my side, can you try deleting your cache at `~/.cache/huggingface/modules/datasets_modules/datasets/InstaDeepAI--nucleotide_transformer_downstream_tasks_revised` and try again ? For some reason `datasets` wasn't able to find the DatasetBuilder class in the python script of this dataset

I've met the same problem when importing [LongBench-v1](https://github.com/THUDM/LongBench/blob/main/LongBench/README.md). the debugger reports `dataset_module.builder_configs_parameters.builder_configs` as `None` so that no `builder_cls` gets created:

does this mean that I need to downgrade `datasets`?

I tried downgrading `datasets` to v2.20.0 and it works fine now...

I think there might be some compatibility issues during code updates between `v2.20.0` and `v3.0.0` 🤔 

also I suggest @nanu23333 to see if downgrading works.

Found the same problem. When I tried to downgrade the datasets to version below v3.0.0, another problem was raised:  `UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb5 in position 1: invalid start byte`


when I use the pip install datasets==3.3, I come across the error。Then I 
```
pip uninstall datasets
pip install datasets==2.21.0
```
It is OK now
