Update dataset_infos for UDHN/udhr dataset
The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/datasets/pr_4362). All of your documentation changes will be reflected on that endpoint. Thanks for contributing @leondz.

The checksums of the files have changed because more languages have been added:
- the new language codes need to be added to the dataset card (README file)
- I think the dataset version number should also be increased, so that users who had previously cached it, get a new dataset download (with the additional languages) Yep! All done (also fixed the language tags in the README which were iso639-3 instead of the expected bcp47) I guess the language code CI failure is due to languages.json being a subset of bcp47 (see issue #4304), happy to contribute a solution here, e.g. autogeneration of the lang list from the relevant isos and the ietf bcp47 subtag register or full code for validation > Thanks again for your contribution, @leondz.

Oh, thanks, I missed that one

Yeah, I saw this :) I already have the merge, thanks. I'm talking about the longer-term picture: every time another language code comes up (e.g. da-bornholm or es-VE), the json will need updating, because the current approach is non-exhaustive manual whitelisting instead of relying on the established bcp standard.
