Here you can see E2E WF running critical tests successfully in CI in a forked repo

https://github.com/puntope/woocommerce-paypal-payments/actions/runs/18312747880/job/52145723971

Basically, is the same as the one in the PR, the reason of forked repo is because GH WF need to be in the default branch to be running so the only way of test it is under forked repo.
