Revert "argument changes to support ruby 3", again

Description

This (re) reverts commit fac4b91

Re fixes #1014, which was unreverted on #1019

Also updates a checksum in a testfile, which was apparently needed to get the tests to pass. I'm not familiar with this codebase, so I'm not sure if that was a typical thing to do or not.
