Add build/release workflow for Linux, Windows, MacOS, FreeBSD and OpenBSD

Add github action release workflow that automatically publishes release with built binary on tags.

Hi! Thanks a lot for your contribution — this is a great idea, and we fully agree that automating release builds and publishing through GitHub Actions would be very useful.

Currently, we build binaries for a wide range of platforms (Windows, macOS, multiple Linux architectures, as well as FreeBSD and OpenBSD), which are available here:
https://www.bredbandskollen.se/om/mer-om-bbk/bredbandskollen-cli/

Your proposed workflow is a solid starting point, but at the moment we don’t have the capacity to set up support for all the platforms we distribute. That said, we’d really welcome any help in extending the workflow to cover more target systems — using cross-compilation or matrix builds, for example.

Thanks again for the initiative — we appreciate it and look forward to improving the release process together!

I have now added jobs to build Linux (amd64, arm64, armhf, i386, mips), Windows (amd64), MacOS (amd64), FreeBSD (amd64), OpenBSD (amd64). I have, however, not tried to run the binaries in their respective environment.

Seems great, and I think PRs would benefit from automatic builds as well

I kind of expected the action to run on this PR, but that probably doesn't kick in until it's merged?

Copilot's take:
If this repository is configured to require approval for workflows from first-time or new contributors, could a maintainer please review and approve the workflow run for this PR? This will allow the CI to execute and validate the new workflow file.

Thank you!

Does this look reasonable? Do you request any further changes before merging?

It is hard to find the time to review your work. But we will try it out when we release the next version of the CLI-client. We are working on a new version at the moment.
Thanks for contributing.

JFYI: not sure whether this applies in case of bbk CLI, though building on very latest Ubuntu runner isn't always beneficial. If the tool depends on very latest glibc, it may fail on older, though still supported versions of Ubuntu. A random illustrative example of what I mean: hougesen/mdsf#1322
