[BUG]: A11Y: About page should not have multiple h1 elements

[dgodongm]

About page has multiple h1 elements.

Expected Behavior

Web pages should only have one h1 and it should generally be for the title

Current Behavior

About page has 2 h1 elements

Possible Solution

At a high level components should not default to having h1. Should be able to have heading level set dynamically based on context. If a default level is specified, then it should be h2.

Steps to Reproduce

1. Navigate to About page (http://localhost:3000/about when running locally)
2. Inspect page or run HeadingsMap browser add-on
