Re-routing to @elastic/developer-docs

What I'd like to see with this is that:

• only the 1st page remains in "Explore and Analyze". The rest is best in the reference docs.
• we turn this remaining page in Explore and Analyze into a page that summarizes where Kibana users in particular can leverage this language. Similarly to what we do with the "ES|QL in Kibana" page.

By "ES|QL in Kibana" you mean this page: https://www.elastic.co/docs/explore-analyze/query-filter/languages/esql-kibana, right?
