Refactor build workflow and release

[aalmiray]

I'm the author of JReleaser, a tool that helps automating releases. The tool is ideal for applications that produce native executables such as yours. JReleaser may be invoked as a Gradle plugin, Maven plugin, Docker image, or as a CLI.

An example of its usage can be found at https://github.com/kcctl/kcctl

I can help setting it up should you be interested in exploring the tool.
