Update getting-started.asciidoc

The connection should be using the cloud id and API key, not the cloud endpoint.

The image unfortunately will need to be updated to as it obfuscates the cloud id and highlights the endpoint copy.

This would be consistent with our docs here
https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/connecting.html#cloud-deployment

Which states always use the cloud id, for our Elastic Cloud Hosted deployments to connect.
