DOC: Update howto-docs with link to NumPy tutorials.

Includes a few textual fixes suggested in gh-16386 and new link to
Daniele Procidas's newly renamed Diátaxis Framework (instead of
 the Divio blog).

+Documentation framework
 ==============================================================================
+
 There are formulas for writing useful documents, and four formulas
 cover nearly everything. There are four formulas because there are four
 categories of document -- ``tutorial``, ``how-to guide``, ``explanation``,
 and ``reference``. The insight that docs divide up this way belongs to
-Daniele Procida, who goes on

-the differences and reveal the formulas. When you begin a document or

+===============
+
+In addition to the documentation that is part of the NumPy source tree, you can
+submit content in Jupyter Notebook format to the
+`NumPy Tutorials <https://numpy.org/numpy-tutorials>`__ page. This
+set of tutorials and educational materials is meant to provide high-quality
+resources by the NumPy project, both for self-learning and for teaching classes
+with. These resources are developed in a separate GitHub repository,
+`numpy-tutorials <https://github.com/numpy/numpy-tutorials>`__, where you can
+check out existing notebooks, open issues to suggest new topics or submit your
+own tutorials as pull requests.
