✅(jest) Declare jest-jasmine2 by name not path

Up-to-now when changing the test runner used internally by Jest, we were passing it the full path to the runner and its entry point. This approach proved fragile when we attempted to switch to Yarn in PnP mode.

This PR change the way we declare the runner: we stop passing the path to the entry point and just pass its name.
