fix: correct GoReleaser Pro configuration for CGO and Docker builds

Problem:
- Used incorrect field names (use: buildx, build_flag_templates) not supported in GoReleaser v2.13.2
- GitHub Actions workflow using non-CGO release workflow
- Docker builds failing due to invalid configuration

Solution:
- Updated dockers_v2 configuration with correct field names:
  - Removed unsupported `use: buildx` field
  - Changed `build_flag_templates` to `build_args` (map format)
  - Kept `platforms` for multi-arch support (linux/amd64, linux/arm64)
- Updated GitHub Actions workflow to use go-release-cgo.yaml for CGO support
- Build args now passed correctly to Docker builds for version info

Changes:
- .goreleaser.yaml: Fixed all Docker image configurations
- .github/workflows/release.yaml: Changed to go-release-cgo.yaml workflow

Validation:
- goreleaser check: PASSED ✓
- Configuration validated with GoReleaser Pro v2.13.2
