Fix broken links and outdated information for documentation of Orbbec camera #23829
Resolves the documentation issue from https://github.com/opencv/opencv/issues/23579.
Orbbec is moving to support UVC directly so they do not provide the old `install.sh` for OpenNI SDK >= 2.3.0.86. Also in their new release of OpenNI SDK, paths of include headers and libraries are changed. Changing our cmake script for this change does not make sense since we cannot make this kind of change everytime they update. So just added a subsection providing `install.sh` for users as a workaround on our side.
