docs: Add some READMEs

@@ -35,6 +35,7 @@ Neolace is 100% written in TypeScript. Here's how the code is organized:
 * __frontend__ - The Neolace frontend, a Next.js React application that implements our standard user interface. Plugins and theme settings can be used to customize the UI, or you can replace it entirely with a custom frontend.
 * __neolace-admin__ - The Neolace Admin Tool, a command-line script that you can use for administrative purposes like importing or exporting data.
 * __neolace-sdk__ - The Neolace Software Development Kit (SDK), which provides TypeScript interfaces for all of the Neolace entities. This code is shared by the frontend and the backend. It also contains an API client which makes it really easy to use the REST API.
+* __sites__ - Example sites/content.
