Attestation Format

Maybe that's a duplicate, so feel free to close this issue if that's the case.

I heard that the format in which the attestation is issued remains to be an open question. Here's a suggestion:

We publish a release of the assessed OSH, annotated accordingly (something like v.1.0.2-attested)
…alongside with Export files etc. and a pretty PDF (something like this: ugly, pretty-1, pretty-2)
optional: we link the repo with Zenodo and automatically provide a DOI to the release (see this guide for GitHub)
