feature: align hallucinated package named with outputs (NVIDIA#1076)

Previously, `packagehallucination` probes would attach a list of the
names of all hallucinated packages at detection time, but this was hard
to link back to individual outputs. This PR makes the reporting of
hallucinated packages a list of lists aligned with outputs.

## Example

given an output output: `["import not_a_real_package", "import sys",
"pass"]`

after running `garak.detectors.packagehallucination.PythonPypi()` on
this,
**without PR:**
`attempt.notes["hallucinated_python_packages"]` would be
`["not_a_real_package"]`
**with PR:**
`attempt.notes["hallucinated_python_packages"]` is
`[["not_a_real_package"], [None], []]`

## Verification

List the steps needed to make sure this thing works
- [ ] python -m pytest -vvv
