FolderBase Dataset automatically resolves under current directory when data_dir is not specified
@lhoestq  Makes sense, I guess this can be fixed in the load_dataset_builder method.
It concerns every packaged builder I think (see values in `_PACKAGED_DATASETS_MODULES`) I think the behavior is related to these lines, which short circuited the error handling.
https://github.com/huggingface/datasets/blob/664a1cb72ea1e6ef7c47e671e2686ca4a35e8d63/src/datasets/load.py#L946-L952

So should data_dir be checked here or still delegating to actual `DatasetModule`? In that case, how to properly set `data_files` here. This is location in PackagedDatasetModuleFactory.get_module seems the be the right place to check if at least data_dir or data_files are passed @mariosasko can you please assign this issue to me,I want to work on this #self-assign @mariosasko is this issue still open? i would love to kickstart my journey to open source with this issue!

### Describe the bug

FolderBase Dataset automatically resolves under current directory when data_dir is not specified.

For example:
```
load_dataset("audiofolder")
```
takes long time to resolve and collect data_files from current directory. But I think it should reach out to this line for error handling https://github.com/huggingface/datasets/blob/cb8c5de5145c7e7eee65391cb7f4d92f0d565d62/src/datasets/packaged_modules/folder_based_builder/folder_based_builder.py#L58-L59

### Steps to reproduce the bug

```
load_dataset("audiofolder")
```

### Expected behavior
