Regression: `injectGlobals:false` no longer supported ("Cannot convert undefined or null to object")

🐛 Bug Report

I'm trying to update Puppeteer, jest-puppeteer and expect-puppeteer to their latest versions and I'm encountering this issue:

 FAIL  test/browser.js
  ● Test suite failed to run

    TypeError: Cannot convert undefined or null to object
        at Function.keys (<anonymous>)

      at Object.<anonymous> (node_modules/expect-puppeteer/dist/index.js:505:8)

The issue appears to happen here:

jest-puppeteer/packages/expect-puppeteer/src/index.ts

Line 168 in ae81ca4

Object.keys(jestExpect).forEach((prop) => {

because jestExpect is undefined

To Reproduce

# Check out https://github.com/fregante/webext-dynamic-content-scripts/pull/63/commits/b428a7823f6317b5f508304f5893e061514967e2

npm install -D jest-puppeteer@latest expect-puppeteer@latest
npm run jest

The same also happens when upgrading to puppeteer 21 without updating those two dependencies.

Expected behavior

The tests should pass (or at least not throw in expect-puppeteer)

Run npx envinfo --system --binaries --npmPackages expect-puppeteer,jest-dev-server,jest-environment-puppeteer,jest-puppeteer,spawnd --markdown --clipboard

If I drop jest.injectGlobals: false from my package.json, v9 works again. It would be great to restore support for this
