Fix current implementation for Algolia #14

TL;DR

Fix the current implementation so that developers can pull the repo and build right away.

🧠 Context

Right now, developers aren't able to build the handbook site due to the new Algolia feature implementation (see below). This is caused from the docusaurus.config.js file not being able to properly read the Algolia variables, such as ALGOLIA_APP_ID.

We want to be able to fix this so that people can locally run the site. This is especially helpful for docs sites since you want to be able to test pages locally before releasing them live.

🛠️ Implementation Plan

TBD

✅ Acceptance Criteria

• Able to run the handbook site locally with no issues
