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

ChromaDB versions earlier than 0.4.13 don't work with pydantic v2. I
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.

## Description
Pretty self-explanatory! list_collections() is an attribute of the
AsyncHttpClient, not of the ChromaDBAdapter, so line 541 should say
client.list_collections() (as indeed line 556 correctly already does).
This will fix the AttributeError I was getting.
This is my first ever PR so let me know if there is anything else I need
to do :)
