probe: add whois injection to latentinjection (#947)

Add tests for WHOIS response injections to `latentinjection` probe.
Resolves #73

## Todo:
* move whois responses into `payload`
* add second probe using same data in a "sandwiched" way like the Eiffel
snippet probe does, simulating a RAG being asked to identify and report
on any malicious domains in a whois DB

## Verification

- [ ] `garak -m test -p latentinjection.LatentWhois`
- [ ] Run the tests and ensure they pass `python -m pytest
tests/probes/test_probes_latentinjection.py`
