complete RDF generation and curation tests

This issue is one for me to track and communicate what remains to be done for the RDF generation.

[x] ~RDF generated files not all under /Human/ but in folders (as in past .zip files)~
[ ] factor out wp:bdb* triple generation based on metadata files
[ ] set up a GitHub Action to generate RDF and push this into a separate repository [Alex, Egon]
[ ] author RDF [Alex]
[ ] VoID header file
[ ] SMILES from Wikidata
[ ] ontologies do not have to be generated, but should be loaded too
