Create About Page for Testimony in the 21st Century

Problem:

In order to make the role/value of MAPLE and public testimony in the digital age more clear to users, we want to add an static page explaining how we see the role of public testimony in the modern day.

Success Criteria:
- Create a new page in the "About" section of the site titled "Testimony in the 21st Century"
- The page should use the same card components as the "How MAPLE Uses AI" about page (at https://maple-dev.vercel.app/about/how-maple-uses-ai)
- The page should have one Card for each bullet point in the "PAGE COPY" section below
- A link to the new page should be added to the About section of the Header and Footer navs

**PAGE COPY**:

**Testimony in the 21st Century**
* Despite this being a “testimony” website, we often struggle to define it!
* “Public testimony” used to be the sole avenue for influencing legislation and creating a record of legislative discussions and intent. But not anymore!
* A “tweet” or viral video can influence legislation (and often does), and civic debate has moved from meeting halls to online forums and feeds.
* While “public testimony” may seem archaic, its underlying goals remain imperative – influencing legislation and documenting legislative discussions.
* Whatever the manifestation of political expression - whether a tweet, post, public comment or testimony - these expressions are essential.
* Perhaps just as essential is the space that elicits, houses and shares those political expressions.
* We, at MAPLE, do not take this responsibility lightly, and neither should you.
* However, you should not be intimidated by the phrase “public testimony”. It should not conjure much more uncomfortability than sharing a tweet or post.
