Scripts: remove checked-in debugger; statements

Summary:
These snuck in, presumably accidentally, via https://github.com/facebook/react-native/pull/49164.

This interferes with running test suites with a debugger connected (e.g, when debugging Jest itself).

(Aside: we should probably enable [`eslint/no-debugger`](https://eslint.org/docs/latest/rules/no-debugger) to catch these)
