CMakeLists.txt: Update version range from 2.8 to 3.31.5 to avoid abort

The error with CMake 4 on the github CI looks like this:

CMake Error at CMakeLists.txt:22 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

CMakeLists.txt: Fix the version for the manual, too
