This change focused on theme and comment/suggestion functionality

I added the starlight-giscus plugin to add giscus support, added an edit page to my config file and followed the steps in the docs for applying a custom theme on a starlight page.

Annoying Bug

When configuring the styling for the giscus plugin in the config, the browser wouldn’t switch neatly when switching from light to dark mode when using themes other than plain light and dark –> using default themes for correct switching logic now.
