Guide should include client mode

Guide should include client mode (similar to the issues I created for others) and put it as the first option.

There's also a left over see also for embedded mode

Docs: Feedback for Get Started with Hazelcast using Spring Boot

Hi, I have some feedback about this page

The example application doesn't work with the current Spring Boot 3 and Java 17. The cluster can't be established with multicast enabled (default). There is an exception thrown.

Changing hazelcast.yaml as follows helps:

hazelcast:
  cluster-name: hazelcast-cluster
  network:
    join:
      multicast:
        enabled: false
      tcp-ip:
        enabled: true
        member-list:
          - localhost:5701
          - localhost:5702

Exception with multicast:

ERROR com.hazelcast.instance.impl.Node : [ip-masked]:5701 [hazelcast-cluster] [5.3.6] Cannot assign requested address: no further information
