Title: `load_dataset` requires a network connection for local download?
State: closed

### Describe the bug

Hi all - I see that in the past a network dependency has been mistakenly introduced into `load_dataset` even for local loads. Is it possible this has happened again?


### Steps to reproduce the bug

```
>>> import datasets
>>> datasets.load_dataset("hh-rlhf")
Repo card metadata block was not found. Setting CardData to empty.

### Expected behavior

loads the dataset

### Environment info

```
> pip show datasets
Name: datasets
Version: 2.18.0
```

Python 3.10.2

Comments: Are you using `HF_DATASETS_OFFLINE=1` ?> Are you using `HF_DATASETS_OFFLINE=1` ?

This doesn't work for me. `datasets=2.18.0`

`test.py`:
```
import datasets

datasets.utils.logging.set_verbosity_info()

ds = datasets.load_dataset('C-MTEB/AFQMC', revision='b44c3b011063adb25877c13823db83bb193913c4')

print(ds)
```

run `python test.py`
```

```

I was having similar inexplicable issues.

Doing this I *think* helped, but, `datasets` still *clearly* does not want to respect the cache:

```python
pip install --upgrade datasets  # now it is 2.18.0
HF_DATASETS_OFFLINE="1" python blah.py
```

Or similarly, I must spacify that env var to resuse the cache, IE, no arg to `load_dataset` helps it reuse the cache:

```python

import os
os.environ["HF_DATASETS_OFFLINE"] = "1"

import logging
logging.basicConfig(level=logging.DEBUG)

import datasets
# >>> datasets.__version__
# '2.18.0'

datasets.utils.logging.set_verbosity_info()
data = datasets.load_dataset("c-s-ale/dolly-15k-instruction-alpaca-format")
```
