Refactor model loading script and add Ollama notebook

- Updated the Modelfile path in `pull-deepseek-model.sh` to use an absolute path for model files.
- Simplified the model loading process by removing unnecessary directory changes and directly referencing the mounted Modelfile.
- Added a new Jupyter notebook `ollama.ipynb` that demonstrates the usage of the Ollama API with a sample query and error handling for unsupported tools.
