ci(winget): inject PAT into git URLs for push auth

gh auth setup-git doesn't reliably register a credential helper when
only GH_TOKEN env is set (no interactive gh auth login), so git push
to the winget-pkgs fork was failing with exit 128. Use a global
url.insteadOf rewrite to embed the token in github.com HTTPS URLs.
