(MODULES-10963) remove win32-process on Puppet 7

Puppet 7 dropped the dependecy on win32-process gem
in favour of monkey patching the Process Module.

As a reppercusion, require `win32/process` will no
longer work on Puppet >= 7.0.0.

This commit updates the reboot task to only require
that specific gem if Puppet < 7.0.0
