Automatically create the package after a release

And then upload it to the created release.
One less step during the release process 💪

We are using that GitHub Actions: https://github.com/shogo82148/actions-upload-release-asset

I've also:
- updated the release script to clone the repo using `https` instead of `git` (otherwise it failed during the build)
- use `md5sum` instead of `md5` because the latest isn't available in GitHub Actions
