Improve documentation for separate version tracks

[p-fischer]

As documented in https://insert-koin.io/docs/setup/v3.2 there are different version tracks for JVM, Android & Android compose libraries now.

However, as #1431 indicates there might still be some confusion.

What confused me was that the changelog https://github.com/InsertKoinIO/koin/blob/main/CHANGELOG.md#321---2022-09-12 didn't announce there is a separate version for Android compose too.

It might help to include the latest version numbers of all tracks in the Readme file and to provide separate release notes.
(What I find confusing is that when koin 3.2.1 was released there was no koin compose version 3.2.1. Now koin 3.2.2 was released and there is koin compose version 3.2.1 but I can't see anything in the release notes.)

Thanks for your feedback.

The idea is to have dedicated milestones per project, like https://github.com/InsertKoinIO/koin/milestone/38

In changelog, a dedicated section is written down.

I can also add a version tag on on each new section, added in documentation. Like (since 3.4.3)
