We assume these tests run across all supported Python versions in CI, and we ensure
consistency with recorded hashes for some well known inputs.
If this fails, then something about the way the python AST works has likely changed.
If Spack is running in a new python version, we might need to modify the unparser to
handle it. If not, then something has become inconsistent about the way we unparse
Python code across versions.
