Fix automatic generation of Zenodo DOI
Other repo maintainers had the same problem with Zenodo. 

There is an open issue on their GitHub repo: zenodo/zenodo#2181
After the last release of Datasets (1.8.0), the automatic generation of the Zenodo DOI failed: it appears in yellow as "Received", instead of in green as "Published".

I have contacted Zenodo support to fix this issue.

TODO:
- [x] Check with Zenodo to fix the issue
- [x] Check BibTeX entry is right
