Update search.mdx

[lizargall]

Docusaurus is so user friendly that you don't need to be a front end developer to use it. I couldn't figure out for the longest time why I kept getting error codes when I tried to test the search bar!

Pre-flight checklist

• [ x] I have read the Contributing Guidelines on pull requests.
• [ N/A] If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• [ N/A] If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

It might seem obvious to some folks, but I stalled for a few weeks trying to figure out why my search bar wasn't working and it was all down to the difference between yarn start and yarn build.

Test Plan

The .md preview looks solid
