Compatibility issue with ESM in ws 8.x

[ai]

🐛 Bug Report

I am using Jest 27 ESM with ts-jest. In recent ws 8.x release, ws got ESM exports, but they do not work with Jest.

import { WebSocketServer } from 'ws'

works in pure Node.js, but leads to error in Jest:

    SyntaxError: The requested module 'ws' does not provide an export named 'WebSocketServer'

To Reproduce

Steps to reproduce the behavior:

Jest config:

{
    "preset": "ts-jest/presets/default-esm",
    "globals": {
      "ts-jest": {
        "useESM": true,
        "isolatedModules": true
      }
    },
    "testEnvironment": "node",
    "coverageThreshold": {
      "global": {
        "statements": 100
      }
    },
    "testPathIgnorePatterns": [
      "<rootDir>/node_modules/",
      "<rootDir>/test/servers"
    ],
    "coveragePathIgnorePatterns": [
      "<rootDir>/node_modules/",
      "<rootDir>/server/index.js"
    ]
  }

tsconfig.json:

{
  "compilerOptions": {
    "target": "es2018",
    "module": "esnext",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "allowJs": true,
    "strict": true,
    "noEmit": true
  },
  "exclude": [
    "**/errors.ts"
  ]
}

index.js

import { WebSocketServer } from 'ws'

export default WebSocketServer

index.test.ts:

import cls from './index.js'

it('is a class', () => {
  expect(typeof cls).toEqual('function')
})

Expected behavior

Pass the test
