Bug report

Bug description:

Sorry I didn't notice this while fixing #134455 but c_api.headers key contains the path to top-level system include directory, i.e.:

{
  "c_api": {
    "headers": "/usr/local/include",
    "pkgconfig_path": "/usr/local/lib/pkgconfig"
  }
}

while according to the examples in PEP 739, it should contain the path to the pythonX.Y directory:

Examples

/usr/include/python3.14
include/python3.14
etc.

CPython versions tested on:

3.14, CPython main branch

Operating systems tested on:

Linux

pythongh-134632: Fix build-details.json to use INCLUDEPY path
bdae884 
Fix ``build-details.json`` generation to use ``INCLUDEPY``, in order to
reference the ``pythonX.Y`` subdirectory of the include directory, as
required in :pep:`739`, instead of the top-level include directory.
