Add GitHub CI action for automated releases that builds and publishes binary releases with `shc`

Follow up for #85 (comment)

For macOS 15 "Catalina" it may be a better solution to bundle a binary version of universalJavaApplicationStub instead of the plain shell script.

The shc utility is able to compile bash scripts to binary and it works! :-)

It's available via brew install shc and can therefore be used easily in GitHub Actions CI.

Done with #96

However, the GH CI runner for macos-11.0 isn't working at the moment and therefore disabled in the builds. See this issue for details: actions/runner-images#2381
