fix(docs): restoring search capability with new public key

[rusackas]

SUMMARY

Docs search wasn't working... @sfirke updated the module (thanks!), but I later saw there's an API key error in my browser console. I searched Algolia for that key, and it looks like they may have rotated it. This is the new one!

Tested locally, and it works.

For those that are thinking "you can't just drop a key into your code like this!," Algolia states:

This is the public API key which can be safely used in your frontend code.This key is usable for search queries and it's also able to list the indices you've got access to.
