Support for @type being an array

[louist7]

There's a bug in the Brick\StructuredData\Reader\JsonLdReader at 151-159:

  } elseif (is_array($type)) {
      $types = array_map(
          fn($type) => is_string($type) ? $this->resolveTerm($type, $vocabulary) : null,
          $types,                          // ← BUG: should be $type, not $types
      );
      $types = array_filter($types);
      $types = array_values($types);
  }

When @type is an array, array_map iterates over $types (the empty array initialised on line 143) instead of $type (the actual array value from the JSON). So every type gets silently dropped.

Suggested fix:

$types = array_map(
      fn($t) => is_string($t) ? $this->resolveTerm($t, $vocabulary) : null,
      $type,   // was $types
  );
