This originally did not use a function because there was a bug in the function, this script is not covered in CI but will remember if this script breaks this is what caused it

IIRC there wasn't a bug in the function, but it was being called with the parameters in the wrong order. https://github.com/ethereum-optimism/optimism/pull/5114/files#diff-8f7bbce915ade563953fda055c7b5c424357da7cc240efd98a70bfce15abf4c1
