Hi, I have a project more or less like react-create-app.
When jest-playwright try resolver playwright instance from project.json there any playwright in dependencies or devdependencies so this fail, because jest and playwright living in another package.
Theres some way to define playwright instance from jest config files?

thanks

@alexgwolff thanks for the report. Seems like the check of package.json for playwright instances should be rewritten.
