Add support for docker.elastic.co/elasticsearch/elasticsearch

[mhalbritter]

We only support elasticsearch from Docker Hub (library/elasticsearch), but we should also support docker.elastic.co/elasticsearch/elasticsearch.

Hi, I'd like to work on this.

My understanding is that the gap is in image-name matching rather than the typed ElasticsearchContainer support, likely in the Docker Compose connection details factory. I’m planning to add support for docker.elastic.co/elasticsearch/elasticsearch and cover it with an integration test.

Thanks for the offer, @carlosSepher, but we already have a PR for this issue: #50119.
