Subject: [PATCH] CI: Publish binaries using GitHub Actions on new tag

Because of time constraints and because the workflow itself
may need some additional work to support multiple operating systems
without making individual releases for every target architecture
and operating system, builds are only generated for Linux (amd64).

New releases are marked as "Drafts" by default, so as to allow
maintainers to edit the text before publication.

Fixes https://github.com/hermit-os/uhyve/issues/256
