Binary build on github CI.

[ghost]

Would it be possible to add a binary release build by the means of github actions?

Since Dockerfile for building already exists, it should be fairly simple to add support for automatically making "releases" with binary files when a tag is pushed?

I am not very familiar with the flow, but it should be something like:

1. Use Github Actions to run a script on new tags. Like this guy does: https://github.com/codebam/resume/blob/master/.github/workflows/build.yml
2. In that script use ghr to create a github release. https://pkg.go.dev/github.com/lowply/ghr
3. The pattern for running on new tags is the following: https://stackoverflow.com/questions/61891328/trigger-github-action-only-on-new-tags

The command for building is already in the Makefile, so this should not be hard?
