🐛 Secuirty Update for Docs Library: Docz -> Astro Docs Migration

[ramazansancar]

Since the document library we are using (https://www.npmjs.com/package/docz-theme-default) is very old and does not receive security updates, I think it would be a good idea to switch to Astro Docs, which is another alternative document library that offers update support.
