[rcruces]

What is the current behavior?

• The notebook plot_tutorial_02_context.ipynb no longer appears in the BrainStat documentation.
• The notebook plot_tutorial_01_basics.ipynb is present but renders without any plots.

Steps to reproduce

1. Open the BrainStat documentation.
2. Navigate to the plotting tutorials section.
3. Note that plot_tutorial_02_context.ipynb is missing.
4. Open plot_tutorial_01_basics.ipynb and observe that no figures are shown.

Expected behavior

• plot_tutorial_02_context.ipynb should be listed in the documentation.
• plot_tutorial_01_basics.ipynb should display its plots correctly.
