Document the HF_DATASETS_CACHE env variable
NONE
Strongly agree to this, in addition, I am also suffering to change the cache location similar to other issues (since I changed the environmental variables).

`HF_DATASETS_CACHE` should be documented there indeed, feel free to open a PR :)

### Feature request

Hello,

I have a use case where my team is sharing models and dataset in shared directory to avoid duplication.
I noticed that the [cache documentation for datasets](https://huggingface.co/docs/datasets/main/en/cache) only mention the `HF_HOME` environment variable but never the `HF_DATASETS_CACHE`.

It should be nice to add `HF_DATASETS_CACHE` to datasets documentation if it's an intended feature.
If it's not, I think a depreciation warning would be appreciated.

### Motivation

This variable is fully working and similar to what `HF_HUB_CACHE` does for models, so it's nice to know that this exists. This seems to be a quick change to implement.

### Your contribution

I could contribute since this is only affecting a small portion of the documentation
