Consider upgrading jupyter-book to >=2.0 #677
Description
Current pin is for >=1.0.4,<2.0, as some of the known limitations with >=2.0 lack features or support for customization used to build the tutorials here (for example, editable inline notebook cells and customization of how jupyter-book is executed). In the future when those issues have been addressed, it may be worth upgrading (although this shouldn't have any substantial effect on the rendered notebooks or the features of the tutorials site).
