in-toto-spec.md: Missing product in 5.3.2 example

[CameronLonsdale]

In section 5.3.2 it states that Alice writes test.py however in the root layout it is missing the specification that Alice creates test.py.

The step:

       {"_name": "write-code",
        "threshold": 1,
        "expected_materials": [ ],
        "expected_products": [
          ["CREATE", "foo.py"]
        ],
        "pubkeys": [
          "<ALICES_KEYID>"
        ],
        "expected_command": "vi"
       },

should be

       {"_name": "write-code",
        "threshold": 1,
        "expected_materials": [ ],
        "expected_products": [
          ["CREATE", "foo.py"],
          ["CREATE", "test.py"]
        ],
        "pubkeys": [
          "<ALICES_KEYID>"
        ],
        "expected_command": "vi"
       },

Unless I have a misunderstanding, this is my first time reading through the document.
