Add GitHub workflow for cross-platform releases

[Jarva]

This GitHub action will trigger automatically when creating a release and will create binaries for 5 common architectures and attach them to the aforementioned release.

Supported architectures (Windows, MacOS, Apple Silicon, Linux gnu/musl):

- { target: x86_64-apple-darwin         , os: macos-12,                                                  }
- { target: aarch64-apple-darwin        , os: macos-14,                                                  }
- { target: x86_64-pc-windows-msvc      , os: windows-2019,                                              }
- { target: x86_64-unknown-linux-gnu    , os: ubuntu-20.04, dpkg_arch: amd64,            use-cross: true }
- { target: x86_64-unknown-linux-musl   , os: ubuntu-20.04, dpkg_arch: musl-linux-amd64, use-cross: true }

Additional steps may be to package the Mac binaries as a DMG and the Linux binaries as a flatpack.

have you tested that it works yourself?

[RealRTTV]

or well... are you able to?

[Jarva]

I've tested the Linux and Apple Silicons builds and they run for me. The macOS build seems to have some scaling issues with high dpi displays but it's not a functionality issue. I'm unable to test the x86 MacOS or the Windows build myself.

[Jarva]

The built artifacts are available on a release on my fork: https://github.com/Jarva/nbtworkbench/releases/tag/1.3.1

[Jarva]

I had someone on Discord test the Windows build, and they reported back all good
