Description

Before fixing this bug, fastify.websocketServer it doesnt have any resolved auto completion/types in vscode, when I open the type definition it throw error TS1259, because ws package use export = Websocket.

I fix this issue when I change import WebSocket from "ws" to import * as WebSocket from "ws" directly in node_modules/@types/fastify-websocket or in this repo type definition

Steps to Reproduce

hovering fastify.websocketServer and open node_modules/@types/fastify-websocket/index.d.ts

Expected Behavior

Expected resolved type definition and autocomplete in vscode
