[extractor] Support default implicit graph in JSON-LD (#1983)
Original PR: https://github.com/ytdl-org/youtube-dl/pull/30229 Per W3C JSON-LD v1.1 §4.9 (non-normative ref): When a JSON-LD document's top-level structure is a map that contains no other keys than @graph and optionally @context (properties that are not mapped to an IRI or a keyword are ignored), @graph is considered to express the otherwise implicit default graph.
