**Problem**

PyInquirer has no longer maintained and not working with recent python.

**Solution**

Use InquirerPy instead.

**Problem**

Since the repository doesn't have packaging configuration for Python
but only for binding, it is not easy to use Python binding.

**Solution**

Add a Python packaging installation in CMake and minimum `pyproject.toml`
file for packaging by using scikit-build-core.

With these changes, users can install and use Python binding by simply
using regular python package manager such as `pip` or `uv`.

Adding the directory to the files list is used to recurse into the subdirectories.
The iterator flag QDirIterator::Subdirectories already does that automatically, so we only need to create the directory, not recurse into it.
