SDK 6 documentation issues

[Robert-Zak]

Regarding building SDK 6 based on documentation https://docs.alfresco.com/content-services/latest/develop/oop-sdk/#prereq
I found 2 issues which makes impossible to build the code.

1. Pom tag 0.0.1-SNAPSHOT makes impossible to download referenced libs du to issue: [BUG] ALFRESCO SDK 5.2.0 bug with dependency - compilation error #223
   Workaround is put value the same as alfresco-java-event-api-spring-boot-starter, for example 6.0-M1

2. Referenced libraries:
   import org.alfresco.event.sdk.model.v1.model.DataAttributes;
   import org.alfresco.event.sdk.model.v1.model.NodeResource;
   import org.alfresco.event.sdk.model.v1.model.RepoEvent;
   import org.alfresco.event.sdk.model.v1.model.Resource;

Are not present in alfresco-java-event-api-spring-boot-starter, version 6.2. The latest version is 6.0-M1
