LF-5362: Upgrade to @datafoodconsortium/connector v2

[SayakaOno]

Description

Upgrade @datafoodconsortium/connector to v2.0.0-beta.2 (CHANGELOG) and restores existing DFC API functionality under the new version.

Breaking changes addressed

• Enterprise → Organization in the adapter and all tests
• dfc-b:hasAddress country field now requires a SKOSConcept object instead of a plain string URI

New in this PR

• Content-Type: application/ld+json; profile="dfc-v2" response header on both DFC endpoints
• GET /dfc/enterprises/ response wrapped in ldp:Container for DFC v2 compliance

Taxonomy file

The v2 release taxonomy is structurally incompatible with the connector's importThesaurus (uses broader only, no ConceptScheme/hasTopConcept). As a workaround, the v1 taxonomy structure is retained with the URI prefix updated to http://w3id.org/dfc/taxonomies/v2.0.0/productTypes.rdf#.

Other changes

• X (Twitter) social media URL updated to x.com
• Linked references (dfc-b:hasAddress, dfc-b:hasMainContact, etc.) are now serialized as plain URI strings instead of {"@id": "..."} objects — this is v2 connector behaviour, semantically equivalent per JSON-LD spec
