    ARROW-18284: [Python][Docs] Add missing CMAKE_PREFIX_PATH to allow setup.py CMake invocations to find Arrow CMake package (#14586)
    
    Following along the build documentation CMake was unable to find the arrow installation when the documentation gets to the point of invoking setup.py. This should fix that and prevent errors like:
    
    ```sh
    CMake Error at /home/willayd/mambaforge/envs/pyarrow-dev/share/cmake-3.24/Modules/CMakeFindDependencyMacro.cmake:47 (find_package):
      By not providing "FindArrow.cmake" in CMAKE_MODULE_PATH this project has
      asked CMake to find a package configuration file provided by "Arrow", but
      CMake did not find one.
    
      Could not find a package configuration file provided by "Arrow" with any of
      the following names:
    
        ArrowConfig.cmake
        arrow-config.cmake
    
      Add the installation prefix of "Arrow" to CMAKE_PREFIX_PATH or set
      "Arrow_DIR" to a directory containing one of the above files.  If "Arrow"
      provides a separate development package or SDK, be sure it has been
      installed.
    Call Stack (most recent call first):
      build/dist/lib/cmake/ArrowPython/ArrowPythonConfig.cmake:54 (find_dependency)
      CMakeLists.txt:239 (find_package
    ```
