[docs] transformers/quicktour rendering issue
There is a rendering issue in https://huggingface.co/docs/transformers/quicktour#trainer-a-pytorch-optimized-training-loop
step 5.

The markdown looks like [this](https://github.com/huggingface/transformers/blob/9e56aff58a742b48fc8edea8d28d5b80330efbcc/docs/source/en/quicktour.mdx?plain=1#L445-L451)

```python
>>> def tokenize_dataset(dataset):
...     return tokenizer(dataset["text"])


>>> dataset = dataset.map(tokenize_dataset, batched=True)
```


but `dataset = ...` renders as a separate triple-indented quote

Transfering to the transformers repo as it's more relevant there cc @sgugger <|||||>Should be fixed by the PR mentioned above.<|||||>Probably not worth looking at more, but just by way of comparison, there is multiple returns on this page that seem to work (again referencing `dataset.map`):

I have no idea if it matters, but when viewed as markdown, there are some sections of the quickstart that don't render right. E.g., see the

```
```py >>> pt_batch = tokenizer( ... ["We are very happy to show you the...
```

in this [section](https://github.com/huggingface/transformers/blob/9e56aff58a742b48fc8edea8d28d5b80330efbcc/docs/source/en/quicktour.mdx#autotokenizer)

<|||||>Thanks for raising this issue! 

It isn't as important when viewed as Markdown because we use a special syntax (`<frameworkcontent>`) to generate the PyTorch and TensorFlow code blocks in our docs.
