feat: use OpenAlex for all unsupported DOI registry agents

ewan-escience commented 1 month ago

Use OpenAlex for unsupported DOI RAs

On the frontend, when searching for a DOI that is not from Crossref or DataCite, use OpenAlex instead
Same when bulk importing on the frontend
Same for the mentions scraper

docker compose down --volumes && docker compose build --parallel && docker compose up --scale data-generation=0
Now that there are no mentions, create a software or project page, search for 10.3968/10006, it should be found using OpenAlex, but don't add it
Do a bulk import of mentions (use e.g. #808) including this DOI, it should be found, import them
Run the mentions scraper (a few times if necessary):
docker compose exec scrapers java -cp /usr/myjava/scrapers.jar nl.esciencecenter.rsd.scraper.doi.MainMentions
The scraped_at field at http://localhost/api/v1/mention should be set, no errors should be generated
Do some more testing with other DOIs (use e.g. #808) to see if everything still works

Closes #1321
