refactor: simplify build and draft release jobs (#30)

- and also fix the zip and release notes publish
- there is no need to unzip and then later re-zip files to be published
as draft because Kotlin does the zip in the first place, we just need to
upload it and download it in the jobs that need it.
- similar, release note files have to be shared between jobs by
upload&download
