Enhance documentation for changelog.json file

[M3lkior]

Hello @tomasbjerre , first, great job !

Is it possible to enhance/write the documentation for changelog.json file content ? no attributes are documented and it's difficult to know how to use them.

Thanks

Yes. Perhaps the json should be documented in the library.

More parameters can definitely be added to the maven plugin. And documented here.

I added some documentation now, is that ok?
