Fix JabKit's `--version` output

[koppor]

Currently jabkit --version outputs nothing:

c:\git-repositories>jabkit --version

c:\git-repositories>

--help outputs the version

c:\git-repositories>jabkit --help

JabKit - command line toolkit for JabRef
Usage: jabkit [-dhpv] [COMMAND]
...
c:\git-repositories>

Wish:

The version is output on the command line#

6.0-alpha.197--2025-11-24--0a9793a

Similar to jbang --version

c:\git-repositories>jbang --version
0.132.1

c:\git-repositories>

Hints

The variable is in place: org.jabref.toolkit.commands.JabKit#versionInfoRequested, but not read yet.

Read on at https://picocli.info/#_version_help for a howto for PicoCLI.

int result = commandLine.execute(args);

It might be that --version is done wrong currently and just a VersionedCommand needs to be implemented.

Run JabKit:

Modify run configuration:

Installing JabKit: https://github.com/JabRef/jabref/tree/main/.jbang#installing-and-running-jabkit-with-jbang - not required to solve the issue but helpful to understand how the outputs above are produced.
