What?
Following work in #2041, identified it would be useful to have some basic spec tests that cover workflow functionality

Why?
Catch regression issues

How?
Add .spec to scripts test in packages\scripts\src\commands\workflow to ensure workflow can be triggered with child workflows, and that all receive and evaluate options as expected

Other details
Whilst trying locally I've had quite a few issues getting the tests to run without executing commander.js commands (or passing additional args to them). Will likely require some extra refactoring on top of writing tests.
