Ruby 3.5 to drop win32ole

[Earlopain]

Ruby is continuing its path of requiring more gems to be specified. win32ole is next on the list (among others) and will start warning in Ruby 3.4: ruby/ruby@f365bef

Usage is here, to get the number of cores on windows:

parallel/lib/parallel.rb

Lines 331 to 336 in f66f105

	require 'win32ole'
	result_set = WIN32OLE.connect("winmgmts://").ExecQuery(
	"select NumberOfCores from Win32_Processor"
	)
	result_set.to_enum.collect(&:NumberOfCores).reduce(:+)
	else

Something like the following may be a suitable replacement:

IO.popen("wmic cpu get NumberOfCores", &:read).scan(/\d+/).map(&:to_i).reduce(:+)

Output of that command:
NumberOfCores \n\n4 \n\n\n\n

I have also openend the same report on concurrent-ruby at ruby-concurrency/concurrent-ruby#1048 if you are interested. Both implementations for this are basically the same.

awesome, thx for the heads up!
I'll wait for concurrent-ruby to address this since they got more manpower :)

I openend ruby-concurrency/concurrent-ruby#1051 if you have some feedback
