Beautify Notebooks and Integrate into Sphinx Documentation as Tutorials

[MarcoHuebner]

Our Jupyter notebooks currently lack a polished appearance, and we're missing an opportunity to showcase them effectively in our Sphinx documentation. Beautifying the notebooks by adding explaining markdown sections and seamlessly integrating them into our documentation will enhance the overall presentation and provide a more engaging experience for users and contributors.

Implementation Steps:

Notebook Beautification:

• Improve the readability and visual appeal of the Jupyter Notebooks by adding more markdown sections

Integration into Sphinx Documentation:

• Add a 'Tutorials' section to the documentation
• Render the beautified notebooks in the Sphinx documentation 'Tutorials' section.
