Remove "Staying connected" static site page

[emyl3]

Description

We have a "Staying connected" page on the static site. This page is not linked in any of our navigation and has a broken YouTube embed to past demo day videos.

As per Dave's feedback below, we should remove the staying-connected page.

WRT to the page as it now exists, I would say delete it. We're not really doing "Demo Day"-style videos anymore afaik. The sprint demos are internal. "Demos not Memos" isn't intended for public consumption either.

It's also mission redundant vs https://www.simplereport.gov/using-simplereport/whats-new/
