[Starlingx-discuss] [docs] Deleting obsolete sub-project release notes links

[Camp, MaryX]

As we prepare for StarlingX Release 5.0, the Docs team is deleting obsolete sub-project release notes links from the main RN landing page.  
We're asking core reviewers from the various sub-projects to give their +1 on the review for this change. [1]
Target Deadline: April 16

Details: 
The StarlingX Release Notes landing page has 13 project-specific Release Notes links (Bare Metal, Clients, Configuration, etc.) [2]
These RN have not been updated since 2018 and are not actively maintained. 
The Docs team agreed that the links to this old info [3] can be deleted from the main RN landing page. 

If you have questions or concerns, please let us know. 
thanks,
Mary Camp
