Issue: Unable to download the Chinese `wikipedia`, the dumpstatus.json not found!
State: closed

### Describe the bug

I tried:
`data = load_dataset('wikipedia', '20220301.zh', beam_runner='DirectRunner')`
and
`data = load_dataset("wikipedia", language="zh", date="20220301", beam_runner='DirectRunner')`
but both got:
`FileNotFoundError: Couldn't find file at https://dumps.wikimedia.org/zhwiki/20220301/dumpstatus.json`

the full report is:

### Steps to reproduce the bug

`data = load_dataset('wikipedia', '20220301.zh', beam_runner='DirectRunner')`

### Expected behavior

download the data

### Environment info

python3.6
latest datasets/transformers version

In the dumps page of the wiki (https://dumps.wikimedia.org/zhwiki/), I found the following dumps:

Maybe the older dumps are not available which caused the downloading failure? 

However, when I changed to the newer version:
```
data = load_dataset('wikipedia', '20220701.zh', beam_runner='DirectRunner')
```

it shows:
```

So I guess adding the latest dumps versions to the `BuilderConfig` may solve the problem? But how to add it?

Hi, @beyondguo, thanks for reporting.

You have all the information in the dataset card: https://huggingface.co/datasets/wikipedia

> Then, you can load any subset of Wikipedia per language and per date this way:
> ```python
> from datasets import load_dataset
> 
> load_dataset("wikipedia", language="sw", date="20220120", beam_runner=...) 
> ```
> where you can pass as beam_runner any Apache Beam supported runner for (distributed) data processing (see [here](https://beam.apache.org/documentation/runners/capability-matrix/)). Pass "DirectRunner" to run it on your machine.
> 
> You can find the full list of languages and dates [here](https://dumps.wikimedia.org/backup-index.html).

Note that you have to pass the language and date as keyword arguments, and the available dates depend on the language and can be found on Wikimedia website.

Also:
> Some subsets of Wikipedia have already been processed by HuggingFace, and you can load them just with:
> ```python
> load_dataset("wikipedia", "20220301.en")
> ```
> The list of pre-processed subsets is:
