Refactor py versioning in package tests yaml. (#185)

Summary:
We want to be able to pip install multipy runtime via setup.py. To do so, we need to install dependencies and use version numbers in the same way as runtime/nightly tests. This PR includes the py versioning changes to package tests' YAML.

Pull Request resolved: #185

Test Plan: No changes to functionality with this PR.
