[Python][CI] Remove use of CMAKE_POLICY_VERSION_MINIMUM on musllinux

[AlenkaF]

Describe the enhancement requested

When adding support for Python 3.14 the musllinux wheels started failing due to

  #14 16.69 CMake Error at /opt/vcpkg/buildtrees/_vcpkg/build/_deps/cmakerc-src/CMakeRC.cmake:37 (cmake_minimum_required):
  #14 16.69   Compatibility with CMake < 3.5 has been removed from CMake.
  #14 16.69 
  #14 16.69   Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  #14 16.69   to tell CMake that the project requires at least <min> but has been updated
  #14 16.69   to work with policies introduced by <max> or earlier.
  #14 16.69 
  #14 16.69   Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

see: #47616 (comment)

Specifying CMAKE_POLICY_VERSION_MINIMUM helped, as per #47616 (comment). In the future it would be better if we can remove the use of it, see #47616 (comment).
