fix: declare correct ws options type

The original string | string[] seems to have been a mistake because the ws package client takes 3 arguments, of which the middle one (protocols) is the string | string[], but it is optional. When it is left out - it becomes the options object instead: https://github.com/websockets/ws/blob/c798dd4ee20efb2d7591b5659839ad05cdb3eb70/lib/websocket.js#L80

The type information is covered in jsdoc: https://github.com/websockets/ws/blob/c798dd4ee20efb2d7591b5659839ad05cdb3eb70/lib/websocket.js#L627

A more complete typing information is exposed by @types/ws, though.
