Github Actions for Elasticsearch/Kibana Docker Images

Run a nightly action (scheduled every 2AM UTC) that will:

• Fetch list of all elasticsearch/kibana image tags and filter/identify latest major versions (> 7.17.4)
• Pull images for each latest major versions (from library/elasticsearch and library/kibana official repositories)
• Add semantic version tags for each image
  • e.g. elasticsearch:8.2.3 image will be tagged with 8.2.3, 8.2 and 8 tags
• Push images to jahia/elasticsearch and jahia/kibana docker repositories

Github action can also be triggered with a manual workflow if needed. There is also an optional DRY_RUN=true parameter to run the script without pushing to the jahia repository for testing purposes.
