Upgrade Ruby to 3.2

Enhancement Request

Upgrade the embedded Ruby version to 3.1. This would align with future plans for integrating with SketchUp, https://forums.sketchup.com/t/ruby-3-is-coming-headers-and-libs-available/202102. I think their reasoning is pretty sound on picking 3.1 vs 3.0 (which Ubuntu 22.04 went with).

That means we may be able to use the conan-center-index ruby recipe too, which starts at 3.1.0: https://github.com/conan-io/conan-center-index/blob/master/recipes/ruby/all/conanfile.py

At least use that as a basis for modernizing our own https://github.com/NREL/conan-openstudio-ruby/ which uses a CMake layer plus some .bat scripts on windows and is a pain to maintain. Ruby 3.x also is supposed to have made significant advances in properly supporting building with MSVC (the ruby/ruby github repo now has a MSVC runner for CI: https://github.com/ruby/ruby/blob/master/.github/workflows/windows.yml )

• Fix #11553 - ruby/3.1.0: build error on all platforms due to wrong prefix conan-io/conan-center-index#11561

We should tentatively plan to upgrade to 3.1 or 3.2. Can discuss offline if any complications of using 3.2 vs. 3.1. If I get public confirmation of some 3rd party tools Ruby version for next release I'll share that here.
