document page 404 not found after redirection

Describe the bug

The redirected page encountered 404 not found.

Steps to reproduce the bug

1. In this tutorial: https://huggingface.co/learn/nlp-course/chapter5/4?fw=pt
   original md: https://github.com/huggingface/course/blob/2c733c2246b8b7e0e6f19a9e5d15bb12df43b2a3/chapters/en/chapter5/4.mdx#L49

By default, 🤗 Datasets will decompress the files needed to load a dataset. If you want to preserve hard drive space, you can pass `DownloadConfig(delete_extracted=True)` to the `download_config` argument of `load_dataset()`. See the [documentation](https://huggingface.co/docs/datasets/package_reference/builder_classes.html?#datasets.utils.DownloadConfig) for more details.

The documentation points to https://huggingface.co/docs/datasets/package_reference/builder_classes.html?#datasets.utils.DownloadConfig

it shows The documentation page PACKAGE_REFERENCE/BUILDER_CLASSES.HTML doesn’t exist in v2.16.1, but exists on the main version. Click [here](https://huggingface.co/docs/datasets/main/en/package_reference/builder_classes.html) to redirect to the main version of the documentation.

But the redirected website https://huggingface.co/docs/datasets/main/en/package_reference/builder_classes.html is 404 not found.

Expected behavior

I Guess the redirected webisite should be
https://huggingface.co/docs/datasets/main/en/package_reference/builder_classes (without .html)
or https://huggingface.co/docs/datasets/main/en/package_reference/builder_classes#datasets.DownloadConfig.

Environment info

Datasets main
