[nav] Standards Overview page

[shawna-slh]

From https://www.w3.org/WAI/EO/wiki/Redesign_-_October_Revisions :

(new doc) Standards/Guidelines — first link is an overview page

• 🚨 The Components of Web Accessibility page? Or the link Standards/Guidelines? If that got an overview page, shouldn’t the other main nav items get their own overview pages, too? – Eric
• I think we need a new page that is titled Accessibility Standards/Guidelines Overview, and can be in the nav probably just "Overview". I do not think we need to have Overview pages for all of the other nav items. ~Shawn

/me 's suggestion comes from previous WG discussions and supported by UT :-)

@yatil - Please create a placeholder page, and I'll populate it when I can get to it — hopefully in the next day or two. Thanks!

For context, that comment was if the actual Standards/Guidelines link worked differently than the other main navigation items. If we add a page Overview with its own sub-nav link, that’s totally :cool: with me! 😎
