elasticsearch examples broken, not updated in the README.md after "Remove spacing from elasticsearch names"

[boTux]

Description

The REAMDE.md isn't showing the elastic plantuml example.

And the example usage is not working after 4b61b39.

Todo

Upgrade README.md :

@startuml
    !include <elastic/common>
+    !include <elastic/elasticsearch/elasticsearch>
-    !include <elastic/elastic_search/elastic_search>
    !include <elastic/logstash/logstash>
    !include <elastic/kibana/kibana>

+    ELASTICSEARCH(ElasticSearch, "Search and Analyze",database)
-    ELASTIC_SEARCH(ElasticSearch, "Search and Analyze",database)
    LOGSTASH(Logstash, "Parse and Transform",node)
    KIBANA(Kibana, "Visualize",agent) 
    
    Logstash -right-> ElasticSearch: Transformed Data
