RFR: 8270117: Broken jtreg link in "Building the JDK" page [v2]

[Magnus Ihse Bursie]

> Paraphrased description from the bug report:
> 
> The "Building the JDK" page has a jtreg download link pointing to <https://ci.adoptopenjdk.net/view/Dependencies/job/jtreg/lastSuccessfulBuild/artifact> but that gets a 404. I believe the correct link is <https://ci.adoptopenjdk.net/view/work-in-progress/job/GetNode/lastSuccessfulBuild/artifact/> , which is not all that easy to find.

Magnus Ihse Bursie has updated the pull request incrementally with one additional commit since the last revision:

  Use link suggested by Severin instead
