[config] fix the load_site_cubicweb() method for to 'new-style' cubes (closes #16059402)
We first try to load the site_cubicweb module from the cubicweb_<cube> package,
and if it fails, revert back to old cube path.
.. _TutosPhotoWebSite:
Building a photo gallery with |cubicweb|
========================================
Desired features
----------------
* basically a photo gallery
* photo stored on the file system and displayed dynamically through a web interface
* navigation through folder (album), tags, geographical zone, people on the
picture... using facets
* advanced security (not everyone can see everything). More on this later.
