Now recommends uninstalling other packages. Fixes #23314.

Example messages:

Please install @playwright/test package before running "npx playwright show-report"
  npm uninstall playwright playwright-firefox
  npm install -D @playwright/test

Please install @playwright/test package before running "yarn playwright show-report"
  yarn remove playwright playwright-chromium playwright-firefox playwright-webkit
  yarn add -D @playwright/test

Please install @playwright/test package before running "pnpm exec playwright show-report"
