Add an 'About the Studio' page to Notify

[em-herrick]

The Public Benefits Studio leadership and Research and Development teams would benefit from a page nested in the Notify.gov footer to hold a broader set of content about the other projects/activities the Studio is working on beyond Notify.

To complete:

• [ ] Build template for this page: notify.gov/studio
• [ ] Link in footer: About the Pubic Benefits Studio
• [ ] Add and style written content: https://docs.google.com/document/d/1lP8I0Jxu0B26cmTGBQcoHCbfSvKKHQBE6gzTL9HUheE/edit?tab=t.0#heading=h.4hjk4us33ypg

As of 11/5 we're waiting final approval from TTS outreach on the content. Can get started building the page when there is free time, but will need final approval before going live.
