What documentation page is affected

https://www.elastic.co/docs/deploy-manage/deploy/cloud-enterprise/ece-install-offline-no-registry

What change would you like to see?

In the air-gapped installation guide, we instruct users to pull :

docker pull docker.elastic.co/cloud-enterprise/elastic-cloud-enterprise:4.1.0
docker pull docker.elastic.co/cloud-release/elasticsearch-cloud-ess:8.18.0
docker pull docker.elastic.co/cloud-release/kibana-cloud:8.18.0
docker pull docker.elastic.co/cloud-release/elastic-agent-cloud:8.18.0
docker pull docker.elastic.co/cloud-release/enterprise-search-cloud:8.18.0
docker pull docker.elastic.co/cloud-release/elasticsearch-cloud-ess:9.0.0
docker pull docker.elastic.co/cloud-release/kibana-cloud:9.0.0
docker pull docker.elastic.co/cloud-release/elastic-agent-cloud:9.0.0

But there is Mismatch in Elasticsearch and Kibana Versions the doc specifies pulling version 8.18.0 of Elastic components, but the installer actually requires:

elasticsearch-cloud-ess:8.18.2

kibana-cloud:8.18.2

Also it says : docker pull docker.elastic.co/cloud-enterprise/elastic-cloud-enterprise:4.1.0 but it supposed to be
docker pull docker.elastic.co/cloud-enterprise/elastic-cloud-enterprise:4.0.1

LGTM but I prefer to keep the latest version variable, let's fix the version variable in the docs-builder repo, as I think we set it to 4.1.0 by mistake!

Created elastic/docs-builder#1687 to fix the {{version.ece}} information!

LGTM!
