Fixes multiple issues
1. llama stack build of dependencies was breaking with incompatible
numpy / pandas when importing datasets
Moved the notebook to start a local server instead of using library as a
client. This way the setup is cleaner since its all contained and by
using `uv run --with` we can test both the server setup process too in
CI and release time.
2. The change to [1] surfaced some other issues
- running `llama stack run` was defaulting to conda env name
- provider data was not being managed properly
- Some notebook cells (telemetry for evals) were not updated with latest
changes
Fixed all the issues and update the notebook.
### Test
1. Manually run it all in local env
2. `pytest -v -s --nbval-lax docs/getting_started.ipynb`
