ci: add Windows runner support to zxc-e2e-test workflow

- Replace helm/kind-action (installs Linux binary on Windows) with a
  chocolatey-based Setup Kind (Windows) step for Windows runners
- Guard Create Diagnostic Script and Setup E2E Tests steps with
  runner.os != 'Windows' (both rely on sudo/Linux shell scripts)
- Add Run E2E Tests (Windows) step using pwsh without Linux
  process-group management (setsid/ionice/ps -o pgid=)
- Guard Generate ASCII Resource Chart with runner.os != 'Windows'
  (calls a Linux shell script)
