Subject: [PATCH] Download of JDK from the Elastic catalog instead of Adoptium
 (#15514)

* Adapted the JDK's download URL creation to intereact with Elastic catalog to get metadata, and return the catalog download link instead of directly pointing to Adoptium API

* Silenced the Download task of JDK to print the full url

(cherry picked from commit 73daec05ed1c2419885b4e5d3421c5c83355e956)
