Implement schema generator

https://github.com/api-platform/schema-generator

To generate schema from ontologies

API-platform Production doesn't include the schema-generator installed (only for dev, as normally users don't change schema after dev)

Check how we could properly integrate dymamic schema generation in production

https://api-platform.com/docs/schema-generator/configuration/#custom-schemas

Start with the schema-generator repository and API Platform's custom schemas configuration documentation linked in the issue. Determine how the production setup currently excludes schema-generator and what dynamic ontology-based generation requires. Done means production can generate schemas dynamically without relying on a development-only installation.
