LP2039483 Subheadings for staff catalog record page

Adds headings level 2, 3, and 4 to the staff catalog's individual record
page to facilitate better in-page navigation for screen reader users.
Styles have been added to negate the font styles usually applied to
headings, so the page is visually unchanged.
