build: add missing dev dependencies for unit tests (#1004)

# What does this PR do?
Added necessary dependencies to ensure successful execution of unit
tests. Without these, the following command would fail due to missing
imports:

```
uv run pytest -v -k "ollama" \
     --inference-model=llama3.2:3b-instruct-fp16
     llama_stack/providers/tests/inference/test_model_registration.py
```

[//]: # (If resolving an issue, uncomment and update the line below)
[//]: # (Closes #[issue-number])

## Test Plan
Run:

```
ollama run llama3.2:3b-instruct-fp16 --keepalive 2m &
uv run pytest -v -k "ollama" --inference-model=llama3.2:3b-instruct-fp16 llama_stack/providers/tests/inference/test_model_registration.py

```

You can observe that some tests pass while others fail, but the test
runs successfully.
