version2.3.2   load_dataset()data_files can't include .xxxx in path
Author: BUAAChuanWang | Pull request: no | State: closed

### Describe the bug

First, I cd workdir.
Then, I just use load_dataset("json", data_file={"train":"/a/b/c/.d/train/train.json", "test":"/a/b/c/.d/train/test.json"})
that couldn't work and 
<FileNotFoundError: Unable to find 
'/a/b/c/.d/train/train.jsonl' at 
/a/b/c/.d/>

And I debug, it is fine in version2.1.2

So there maybe a bug in path join.

Here is the whole bug report:

### Steps to reproduce the bug

1. Version=2.3.2
2. In shell, cd workdir.(cd /a/b/c/.d/)
3. load_dataset("json", data_file={"train":"/a/b/c/.d/train/train.json", "test":"/a/b/c/.d/train/test.json"})

### Expected behavior

fix it please~

### Environment info
