chore: format expected output

    This sometimes works in our pipeline and sometimes works locally without the formatting.

    I'm not actually particularly sure why, but adding in the expected formatting should make this pass reliably.

    NOTE: When I ran yarn lint --fix after the linter failed, it did a lot more formatitng than expected.
    The only actual non-formatting changes to this file are in the last test on lines 2078 through 2099.
