'Repo card metadata block was not found' when loading a pragmeval dataset
### Describe the bug

I can't load dataset subsets of 'pragmeval'.

The funny thing is I ran the dataset author's [colab notebook](https://colab.research.google.com/drive/1sg--LF4z7XR1wxAOfp0-3d4J6kQ9nj_A?usp=sharing) and it works just fine. I tried to install exactly the same packages that are installed on colab using poetry, so my environment info only differs from the one from colab in linux version - I still get the same bug outside colab.

### Steps to reproduce the bug

Install dependencies with poetry

pyproject.toml
```
[tool.poetry]
name = "project"
version = "0.1.0"
description = ""
authors = []

[tool.poetry.dependencies]
python = "^3.10"
datasets = "2.16.0"
pandas = "1.5.3"
pyarrow = "10.0.1"
huggingface-hub = "0.19.4"
fsspec = "2023.6.0"


[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"
```

`poetry run python -c "import datasets; print(datasets.get_dataset_config_names('pragmeval'))`

prints ['default']

### Expected behavior

The command should print

```
['emergent',
 'emobank-arousal',
 'emobank-dominance',
 'emobank-valence',
 'gum',
 'mrda',
 'pdtb',
 'persuasiveness-claimtype',
 'persuasiveness-eloquence',
 'persuasiveness-premisetype',
 'persuasiveness-relevance',
 'persuasiveness-specificity',
 'persuasiveness-strength',
 'sarcasm',
 'squinky-formality',
 'squinky-implicature',
 'squinky-informativeness',
 'stac',
 'switchboard',
 'verifiability']
```
