[DOC] removed deadlinks from the events/conferences; replaced with videoplay list from early Spark Summits

 - Removed deadlinks from events/conferences
 - spark-summit.org website archives no longer accessible, resulting in a 404 error page; not a good look for the page
 - replaced with a playlist of the most recordings from previous Spark Summit years (2013-2017)

Closes #640 from dmatrix/br_jsd_remove_more_deadlinks_community_page.
