Nanobind example doesnt work for different python version than 3.12.* on windows

[tdejager]

When running the pixi-build-workspace example we now explicitly use 3.12.* for python. Changing this to any other python version breaks the installation of the package with:

 CMake Error at %BUILD_PREFIX%/Library/share/cmake-3.31/Modules/FindPackageHandleStandardArgs.cmake:233 (message):
 │ │   Could NOT find Python (missing: Development Development.Module
 │ │   Development.Embed) (found suitable version "3.13.1", minimum required is
 │ │   "3.8")

It doesn't work on linux either. I get:

Error: 
  × failed to extract metadata for 'python_bindings'
  ├─▶ failed to communicate with the build backend (pixi-build-cmake)
  ├─▶ ErrorObject { code: InvalidParams, message: "Invalid params: unknown variant

  ╰─▶ ErrorObject { code: InvalidParams, message: "Invalid params: unknown variant

That looks like this problem @jc211 - solution in the comments: #2942
