Update to starter colab notebook for lm-eval-harness

[sepiatone]

There has been a refactor of lm-eval-harness a few months ago. The starter colab notebook for lm-eval-harness, linked to from this section has to be slightly updated to reflect this.

Instead of

!python lm-evaluation-harness/main.py \
    --model gpt2 \
    --tasks truthfulqa_gen \
    --device 0

we have

!lm-eval --model hf --model_args pretrained=EleutherAI/Pythia-70m --tasks truthfulqa_gen --device 0
