Docs: Feedback for Hazelcast editions and distributions

Hi, I have some feedback about [this page](https://github.com/hazelcast/hz-docs/edit/main/docs/modules/getting-started/pages/editions.adoc)

It says in one of the Notes:

> Enterprise Edition features are marked with an Enterprise Edition label in this documentation. All pre-existing Hazelcast licenses, such as the Pro/Enterprise/Enterprise HD licenses, are valid for Hazelcast Platform. Each edition has its own installation file i.e. you can’t turn a Community Edition into an Enterprise Edition by adding a license key.

I know it is technically accurate because you have to have a different binary. However it could give an impression that you can't easily go from community to enterprise. In [this page](https://docs.hazelcast.com/hazelcast/5.7/migrate/rolling-restart) it talks about how to go about migrating from community to enterprise. Perhaps in the "editions" doc, in the note or around there, we could say - for more information about going from community to enterprise, see [here](https://docs.hazelcast.com/hazelcast/5.7/migrate/rolling-restart).

Start in docs/modules/getting-started/pages/editions.adoc and read the note describing edition binaries and licenses. Compare it with the migration guidance at migrate/rolling-restart, then add a clear reference for moving from Community Edition to Enterprise Edition. Done means the editions page links readers to the migration guidance without changing the technical statement.
