Set it back to ready for review after double-checking it's the API we need.

light suggestion: prefer using assign!:

Suggested change

	let mut request = knock_room::v3::Request::new(room_id_or_alias);
	request.reason = reason;
	request.via = server_names;
	let request = assign!(knock_room::v3::Request::new(room_id_or_alias), { reason, via: server_names });
