Requesting model `orca-2-7b` raises `llm.UnknownModelError`

[caufieldjh]

Issue c/o Bart Kleijngeld:

Using the llm package to call orca-2-7b directly works as expected:

$ llm -m orca-2-7b "Hi!"

Hello! How can I help you today?

But attempting an extraction with ontogpt fails:

$ ontogpt extract -t drug -i example.txt -m ORCA_2_7B
Traceback (most recent call last):
  File "/home/harry/ontogpt/.venv/lib/python3.10/site-packages/llm/__init__.py", line 148, in get_model
    return aliases[name]
KeyError: 'orca-2-7b'

During handling of the above exception, another exception occurred:

Same version of llm in both cases:
