Adding front matter to help promote the latest version of Zowe Docs articles in Google searches

Is your request for enhancement related to a problem? Please describe.

Currently, Google is indexing older versions of Zowe Docs articles, which means that the latest version of articles are not included in search results. This can lead to Zower users getting outdated information if they're not aware that they've landed on an older version of Zowe Docs.

Describe the solution you'd like

Apply annotations to help alert Google that older versions of Zowe Docs articles should be ignored when a latest version is available.
