Summary:
This fixes how ES modules are handled in Jest tests in the react-native codebase.
They caused some problems before because `import` statements weren't inlined as `require` calls were, so there were some errors in tests when migrating from CommonJS to ESM.
This changes the transform that Jest uses to inline import statements the same way, so we can migrate everything without issues in tests.
