@wordpress/e2e-test-utils-playwright no longer works in Playwright for non-Gutenberg projects #78963

Description

As of 1.48.0, @wordpress/e2e-test-utils-playwright no longer can be used by Playwright outside of gutenberg. All uses of the import have the following error:

> playwright test --trace on

SyntaxError: Unexpected token 'export'

   at admin.spec.ts:1

> 1 | import { test, expect} from '@wordpress/e2e-test-utils-playwright';
    | ^

The problem is that the js files are no longer included in the package and Playwright will not transpile anything in the node_modules directory. This is why it works just fine in Gutenberg itself but doesn't work if used in other Playwright projects.

Step-by-step reproduction instructions

1. Install @wordpress/e2e-test-utils-playwright in a playwright project
2. Try to import from the package. You'll get SyntaxError: Unexpected token 'export'
