Feature: inlude the canonical info hash group in the torrent details response

[josecelano]

Add to the responses (torrent details and after updating a torrent) the list of info-hashes that belong to the same canonical info-hash. Table torrust_torrent_info_hashes

CREATE TABLE "torrust_torrent_info_hashes" (
	"info_hash"	TEXT NOT NULL,
	"canonical_info_hash"	TEXT NOT NULL,
	"original_is_known"	BOOLEAN NOT NULL,
	PRIMARY KEY("info_hash"),
	FOREIGN KEY("canonical_info_hash") REFERENCES "torrust_torrents"("info_hash") ON DELETE CASCADE
);

New response for torrent details:
