fix: text size tokens for Tabs

[jaredcwhite]

Issue Overview

This PR addresses #55

Description

The text size of small tabs should be smaller (right?) than the normal tabs. That wasn't the case once the global semantic text size tokens got renamed, so this fixes it.

How Can This Be Tested/Reviewed?
