## Description 

This introduces a test runner for `sui-move` that just runs shell
scripts and snapshots the output. It also adds a handful of tests for
`sui-move new`.


## Test plan 

It is tests. I did temporarily change some things locally to ensure that
the tests were actually catching some errors
