docs: 🐛 enable quartodoc dynamic lookup (#948)

## Description

This fixes the issue of quartodoc documenting the module/file instead of
the function within the file with the same name.

By actually loading the package (what they call "dynamic lookup"), I
think `core`'s namespace (i.e., `__all__` in `__init__.py`) becomes
available for quartodoc. This is instead of quartodoc using static
analysis to look up the objects we want to document (which is the
default).

It now looks like this for `create_package_structure` locally:
