Freedoms page: the headings hierarchy skips one level

[afercia]

In the Freedoms page wp-admin/freedoms.php, the headings hierarchy skips one level.

All the h3 headings should be bumped up by one level.

[afercia]

49838.diff​ tries to adopt the CSS new naming convention specific to the "about.css" file. It introduces a CSS class has-smaller-headings to visually render H2 like they were H3. Please do let me know if this approach is OK @melchoyce @ryelle

Patch applied, h2s are styled smaller to match h3

[ryelle]

Default h2, no styles applied to shrink them

I've attached a screenshot of the patch applied. For curiosity I also added a screenshot of using default h2s, which probably are too big :) So shrinking them down makes sense. I would change the class to be on the headings themselves, since that's what they affect— something like is-smaller-heading.

Thanks. Patch updated.
