code copy button on the website doesn't copy `...` lines
# 🐛 Bug

## Information

When the copy button is clicked on a code like [this](https://huggingface.co/transformers/quicktour.html#using-the-tokenizer):

```
>>> pt_batch = tokenizer(
...     ["We are very happy to show you the 🤗 Transformers library.", "We hope you don't hate it."],
...     padding=True,
...     truncation=True,
...     return_tensors="pt"
... )
```

only the first line is copied. 

All lines starting with `>>>` get copied, but `...` lines are ignored. So for example, [this](https://huggingface.co/transformers/quicktour.html#customizing-the-model) gets fully copied:

```
>>> from transformers import DistilBertConfig, DistilBertTokenizer, DistilBertForSequenceClassification
>>> config = DistilBertConfig(n_heads=8, dim=512, hidden_dim=4*512)
>>> tokenizer = DistilBertTokenizer.from_pretrained('distilbert-base-uncased')
>>> model = DistilBertForSequenceClassification(config)
```

I was told that this is the issue with `sphinx_copybutton` and I found an already opened issue there:
https://github.com/executablebooks/sphinx-copybutton/issues/65

So hopefully it gets fixed over there, and then the website can be updated to include the fix.

<|||||>this seems to have been fixed in sphinx - I re-checked and it works now.
