Create workbooks for the katas/tutorials, part 2

(This issue is the second part of #208)

The katas offer a set of programming exercises on quantum computing and reference solutions to them, but we often hear that it would be helpful to have the solutions explained, with the logic steps necessary to arrive from the problem description to the code spelled out. It is especially important for people who go through the katas on their own, without a study group to support them.

To address this, we came up with the idea of "workbooks" - explanations of the solutions to the tasks offered in the katas/tutorials, written in Jupyter Notebook format. You can check any of the workbooks completed in #208 to get an idea of what the workbooks look like.

Here are the katas and tutorials that don't have a workbook yet and seem like a good fit for one.
