Create Documentation for Switching between EFK and PLG

Currently, the way to switch from the default EFK stack to PLG is to set the following:

logging:
  enabled: false // Disables the Elasticsearch Kibana deployment

loki:
  enabled: true // deploys Loki

promtail: 
  enabled: true // Deploys Promtail
      
eckoperator: 
  enabled: false // Don't need the eck operator either
  
fluentbit:
  enabled: false // Disables fluentbit

There should be a document to show how to change to the PLG logging stack and what flags need to be enabled/disabled.
