Update default tutorial:
1. Use tutorial from [notebook_tutorial
branch](https://github.com/topoteretes/cognee/blob/notebook_tutorial/notebooks/tutorial.ipynb),
specifically - it's .zip version with all necessary data files
2. Use Jupyter Notebook `Notebook` abstractions to read, and map `ipynb`
into our Notebook model
3. Dynamically update starter notebook code blocks that reference
starter data files, and swap them with local paths to downloaded copies
4. Test coverage

made some changes to the adapter to make it work for versions >= 0.6,
and I changed the chromadb version in the `pyproject.toml` file.
