[Fix][Doc]Move the introduction of map-store configuration to the SeaTunnel Engine Network Services section

[xiaochen-zhou]

Purpose of this pull request

The introduction of map-store configuration is inconsistent between the chapters in separated-cluster-deployment.md and hybrid-cluster-deployment.md. I think it should belong to the hazelcast.yaml configuration content and perhaps should be unified in section 5.3.

Does this PR introduce any user-facing change?

no

The section 5 named Configuring SeaTunnel Engine Network Services. So I think we should not put Imap Configuration in here. It is a part of Configure SeaTunnel Engine

I found hybrid-cluster-deployment.md like this, maybe we should change the section title

By the way, can you help us organize the same configuration of these two documents into a new document? It is a bit cumbersome to maintain two identical documents at the same time.

OK.
