serializers: add RO-Crate metadata serializer

[slint]

• See metadata schema at https://www.researchobject.org/ro-crate/1.1/metadata.html
  • We're aiming at supporting the minimum/required fields for now (and can improve in a future task)
• Should be roughly the reverse of the equivalent deserializer (see https://github.com/inveniosoftware/invenio-rdm-records/issues/1100).

It would be super cool to have RO-Crate in Invenio. We have added it recently to Galaxy and also created a Galaxy Invenio exporter that can "speak" RO-Crate.
