VSP Landing: Update Q&A Section to allow for displaying past and future sessions

[tylergaw]

This section is currently only set up to display future Q&A sessions.

• We want to update to so we can display past sessions too.
• We also want to change up the design a bit so it makes sense for linking to the past session videos and YouTube.
• Play with some type of "video" looking graphic to make it clear

We wanted to get the links to the video up on the site, so for now we put them on landing page, in the body and session note 6a89525
