[Docs] Build fails due to missing Ninja

[abetomo]

Describe the bug, including details regarding any error messages, version, and platform.

I built it on Ubuntu22.04 according to Building Arrow C++.
Then I get an error.

$ cmake .. --preset ninja-debug-minimal
Preset CMake variables:

  ARROW_BUILD_INTEGRATION="OFF"
  ARROW_BUILD_STATIC="OFF"
  ARROW_BUILD_TESTS="OFF"
  ARROW_EXTRA_ERROR_CONTEXT="ON"
  ARROW_WITH_RE2="OFF"
  ARROW_WITH_UTF8PROC="OFF"
  CMAKE_BUILD_TYPE="Debug"

-- Building using CMake version: 3.22.1
CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!
See also "/home/xxx/arrow/cpp/build/CMakeFiles/CMakeOutput.log".

After installing ninja-build, I can build.

I propose to update the document.

Can you propose your diff as a PR. It looks like a good addition to me. You can (I think) click the "edit" icon on https://github.com/apache/arrow/blob/master/docs/source/developers/cpp/building.rst and create a PR that way.

Thank you for your comment.
