Add documentaton for dataset README.md files
Hi ! There's the tagging app at https://huggingface.co/datasets/tagging/ that you can use.
It shows the list of all the tags you can use.

It is based on all the tag sets defined in this folder:
https://github.com/huggingface/datasets/tree/master/src/datasets/utils/resources
Hi,
the dataset README files have special headers.
Somehow a documenation of the allowed values and tags is missing.
Could you add that?

Just to give some concrete questions that should be answered imo:
- which values can be passted to multilinguality?
- what should be passed to language_creators?
- which values should licenses have? What do I say when it is a custom license? Should I add a link?
- how should I choose size_categories ? What are valid ranges?
- what are valid task_categories?

Thanks
Philip
