Create GH release in release script

What about [creating the release](https://docs.github.com/en/rest/releases/releases?apiVersion=2022-11-28#create-a-release) as a draft, so that we need only edit it a bit? It's a nice touch with one curl invocation :)

Look for the existing release script in the repository, likely a shell script. Examine how it currently works and where to add a curl command to create a draft GitHub release via the GitHub API. Check the linked PR discussion for context on the desired workflow. Test the script locally to ensure it creates a draft release correctly.
