Add content on best practices for reproducibility with Jupyter Notebooks

Pythia’s educational materials cover many of the technologies and practices that are vital to Open Science principles such as transparency, accessibility, and reproducibility. But for a scientist not accustomed with many of these technologies, putting everything together in a way that allows them to create a shareable, reproducible workflow may not be obvious. Pythia should consider adding a section that leverages the Foundations modules and provides more of a step-by-step guide to creating a reproducible workflow with a Jupyter Notebook, backed by GitHub and conda. The guide might include a template repo with a Notebook and conda environment management (a slimmed down version of the cookbook template), and a discussion on best practices.

Review the existing Foundations modules and the cookbook template first to understand how educational content and example repositories are organized. Define a step-by-step reproducible-workflow guide using a Jupyter Notebook, GitHub, and conda, optionally with a slimmed-down template repository. Done means the guide covers the proposed best practices and provides a usable example workflow.
