Description

Look into ways we could support Fontawesome 6. They have their own plugin and composer package these days for managing icons: https://fontawesome.com/docs/web/use-with/wordpress/

Why it's Important

To take advantage of new icons.

Possible Implementation

See link above. We might want to consider dropping the baked-in support for icons in this theme in favor of strictly using the plugin/composer package.
