Benjams/fix bioasq card

[BenjSz]

Hi @elronbandel

I made 2 things:
1 - I fixed the bioasq card - we had an error there.

2 - the clapNQ - we point now to the HF for accessing the dataset

However, this main fails on clap_nq!
And I do not succeed to understand why

`from typing import Literal

from datasets import Dataset
from unitxt import load_dataset

def access_to_card(
dataset_name,
card_type: Literal["documents", "benchmark"],
split: Literal["train", "test"],
) -> Dataset:

template = "empty" if card_type == "documents" else "default"
dataset_query = f"card=cards.rag.{card_type}.{dataset_name}.en,template_card_index={template}"
d = load_dataset(dataset_query)
return d[split]

if name == 'main':
for d_name in [
'bioasq',
'clap_nq'
]:
# Benchmark
for s in ['train',
'test'
]:
print(f"#Benchmark ({s}) for {d_name} : {len(access_to_card(d_name, 'benchmark', s))}")
# Documents:
print(f"#Documents for {d_name} : {len(access_to_card(d_name, 'documents', 'train'))}")

`
