DOC: Bundled license file misses empty lines

[stefan6419846]

Issue with current documentation:

When downloading the current binary wheels like numpy-1.26.1-cp39-cp39-manylinux_2_17_x86_64.manylinux2014_x86_64.whl, the bundled LICENSE.txt looks odd for the repository and source licenses section start:

[...]

The NumPy repository and source distributions bundle several libraries that are
compatibly licensed.  We list these here.

Name: lapack-lite
Files: numpy/linalg/lapack_lite/*
License: BSD-3-Clause
  For details, see numpy/linalg/lapack_lite/LICENSE.txt

Name: tempita
Files: tools/npy_tempita/*
License: MIT
[...]

As you can see, the introduction for the bundled libraries is packed directly after the BSD-3-Clause license disclaimer of the package itself.

Idea or request for content:

To improve readability, this should probably changed to introduce some additional newlines or use the formatting as for the other bundled libraries further on.

That happens here, so either the script should be changed to add a newline, or the LICENCES_bundled.txt should be modified to prepend lines like the OS specific fragments.
