Remove dependency on win32ole

[Earlopain]

This gem is being bundled in Ruby 3.5: ruby/ruby@f365bef

So, just use buildin commands to do the same thing.

The powershell version will work on at least Windows 8 (from 2012). There are no docs I could find for earlier versions, so it might work on even earlier versions. https://learn.microsoft.com/en-us/powershell/scripting/install/powershell-support-lifecycle?view=powershell-7.4. Fall back to the deprecated wmic if it doesn't exist.

I have openen grosser/parallel#346 and ruby-concurrency/concurrent-ruby#1051 which do the same thing.

Thanks 👍 I confirmed your powershell script is working correctly.
