chore(docs): bump docusaurus dependencies

[ndom91]

Reasoning 💡

Updated docusaurus dependency's to their latest version. The beta.16 was a relatively big release on their part.

• They changed the light/dark mode switch to a button that looks much nicer with the other nav bar buttons.
• Algolia/Docsearch was updated to 3.0.0 stable, which matches up with the new "AlgoliaCrawler" product we're using on their end (deets)
• Added support for arbitrary HTML in the sidebar (i.e. for logos, custom items, etc.)
• Added nice breadcrumbs
• etc.

Aloglia update required new appId and apiKey. These are both public so no worries 👍

I didn't realize until reading these migration docs now, but old indexes not migrated to these new keys have been frozen and read-only since Feb 1 apparently.

Had to do a few dummy commits to get Vercel to not cancel the deployment and double check algolia was still working 😅

All good though, ready to merge imo 👍
