Instead of generating twice a definition for 2 different formats, we generate the json one and reference the json format inside the jsonld format:

When generating a single resource on our TestBundle we lower the OpenAPI file size quite a bit:

• 12K on 4.1
• 8.0K with this patch

Left to be done:

• check if serialization groups work
• fix feat(jsonschema): make JSON-LD specific properties required only in the schema for output #6485
• tests
