Summary:
This commit updates the documentation configuration so that if an API (function or class) is used in tutorials, then it automatically add the links to the tutorials.

It also adds `py:func:` so that it's easy to jump from tutorials to API reference.

Note: the use of `py:func:` is not required to be recognized by Shpinx-gallery.
