BREAKING CHANGE(output): make `--json` parseable again

### Summary
In v7 we broke the ability for users to parse `stderr` vs. `stdout` output when `--json` is passed.

### Exit Criteria
- [x] revert to using `console.log()` vs. `console.error()` [here](https://github.com/npm/cli/blob/lk/all-deps/lib/utils/exit-handler.js#L212)
