setup: Add LSP builds to release

[flofriday]

Currently the pre-release of 0.3.0 doesn't inlcude any LSP builds.

For the LSP it's also important that we include a Windows build as we cannot ensure that the editor runs on Linux/macOS. Do we know of any reasons that would block us from providing Windows builds?

We have no Windows CI runner. Unfortunately, I have no experience in Windows software development, so I don't know if we can cross-compile to windows.

For the LSP it might be fine to use the JVM distribution for now, as it is not as short running as the CLI.
