Lock jest peer dependency to version 26 or 27

[bodograumann]

Fixes #793

The package is not yet compatible with jest 28 and will currently break after npm update, if the user has not accidentally locked down a specific jest version themselves with:

TypeError: Jest: Got error running globalSetup - /home/bodo/my-project/node_modules/@storybook/test-runner/playwright/global-setup.js, reason: Class extends value # is not a constructor or null

Good one @bodograumann! I think the package.lock file should be updated too
