Release deb packages for other architectures (arm64)

I'm building a Docker image to serve swagger-ui.

But I cannot use apt-get install since https://dl.bintray.com/go-swagger/goswagger-debian only contains amd64 packages. I see on https://github.com/go-swagger/go-swagger/releases/tag/v0.25.0 that you also build for other architectures, so it would be nice to also have them available in the apt repository.
