The order of documentable packages is unstable. It can affect order of packages in a navigation menu.

Presumably it happens due to unstable order of source files. The order (traversing) of files depends on a system (linux/windows) https://github.com/Kotlin/dokka/actions/runs/6630172896/job/18012742052?pr=3227.

See the test two classes from different packages, but more tests of package order are required.
