Interactors from stripes-testing cannot be imported by cypress tests in other packages

Steps to reproduce:

• npm init a new empty package
• install cypress and @folio/stripes-testing
• import { Button } from '@folio/stripes-testing/interactors'; in a cypress test and run it

You'll find that it chokes on optional chaining (eg. ?.) in one of the other interactors:

Error: Webpack Compilation Error
../node_modules/@folio/stripes-testing/interactors/quickMarcEditor.js 18:67
Module parse failed: Unexpected token (18:67)

If you copy the interactors directory into your repo and use it from there, it'll work. So what I expect is happening is that Cypress defaults to doing some transpilation on local imports but expects imports from other packages to already be transpiled.

The really weird part of it for me is this: what is parsing the script that's even complaining about optional chaining? Both the version of node I'm running Cypress from and the version of Chrome it's running the test in support that feature ...so how is this even a problem!?
