[skeleton] Have setuptools install data files
Just add `include_package_data=True` as recommended by
`setuptools documentation`_ as this appears to be the simplest way to handle
this.
Related to #13001466.

Documentation
~~~~~~~~~~~~~
Please keep rules semantically linked grouped together, with a comment about
what they are for.
Recommendation
~~~~~~~~~~~~~~
- Try to use existing classes rather than introduce new ones
- Keep things as simple as possible while in the framework
- Think about later customization by application
- Avoid introducing a new CSS file for a few lines of CSS, at least while the
framework doesn't include packing functionalities
