Changed Windows package manager priority order:
- OLD: chocolatey → scoop → winget
- NEW: winget → chocolatey → scoop

Winget is built into Windows 11, more reliable, and officially supported.
This fixes rubocop installation on Windows systems with both PMs installed.

Fixes issue where chocolatey was selected as primary PM even though
winget was available, causing rubocop to fail (no choco package defined).
