server not launching when persistence is used

[dignakov]

Describe the bug
starting the server with persistence seems to not work

To Reproduce

1. in a terminal (dbDir exists)
2. HOST=localhost PORT=1234 YPERSISTENCE=./dbDir npx @y/websocket-server
3. results in an error:

Persisting documents to "./dbDir"
file:///home/me/.npm/_npx/17f6bbf3c399f7d5/node_modules/@y/websocket-server/src/utils.js:33
  const LeveldbPersistence = require('y-leveldb').LeveldbPersistence
                             ^

ReferenceError: require is not defined in ES module scope, you can use import instead
This file is being treated as an ES module because it has a '.js' file extension and '/home/me/.npm/_npx/17f6bbf3c399f7d5/node_modules/@y/websocket-server/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

Node.js v23.1.0

Without ypersistence it runs fine.
