Set up Algolia search

[bahmutov]

Now after improving the Algolia search for main documentation site cypress-io/cypress-documentation#2668 (which includes scrubbing these examples too, but with lower rank), it would be trivial to set up separate Algolia app and index to scrape the https://example.cypress.io/ site

How to set up scraping: https://glebbahmutov.com/blog/scrape-static-site-with-algolia/
Then we can add the search widget to the navigation element of each page.

We can even keep the scraper as a job in this repository to be executed only on master after new site deploy.

I've been using it with Laravel Scout and to be honest it was far away from my comfort zone to use Algolia without it, but you guys made it look easy...
