[CI-Examples] Change the license of all examples to BSD-3-clause

The CI examples had the default license of LGPL-3.0. With this commit, we change the license of all Makefiles, manifest templates, config files, Python scripts in examples to a BSD-3-clause license. This change is permitted by the "Examples Exception" to the Technical Charter, enacted on 5. December 2023. This change was agreed by all contributors to CI examples, past and present. This change is in response to a popular request to adopt a more permissive license for our examples. The new BSD-3-clause is a permissive license (in contrast to the previously applied copyleft LGPL license). BSD explicitly allows to modify and use our examples without any obligation to share these modifications. Signed-off-by: Dmitrii Kuvaiskii <[email protected]>
