DRAFT: Add localizability content to Pajamas

Purpose

For some time Pajamas included a placeholder page for internationalization (i18n), however, there was no clear path on how or what to document as it related to UX and technical writing.

A recent conversation with a member of the Globalization Technology team shed some light on the need for this content to exist in Pajamas along with how we can get started framing it up. This issue is to create that framework, eventually resulting in a merge request that will add a new "localizability" page under the Content section of Pajamas.
