Integrate Algolia Docsearch

[HarshCasper]

Description

Enarx Docs can greatly benefit by having an integrated search option to help users navigate across the docs and the website. Since the docs are built and hosted, using Docusaurus we can benefit easily by integrating Algolia Docsearch:

• https://docusaurus.io/docs/search#using-algolia-docsearch
• https://github.com/facebook/docusaurus/blob/0e6ec24aa3c431571aaaec61ae0295984dbf8ee9/website/docusaurus.config.js#L337-L342

To avail the API key and integration code, we would need to apply here: https://docsearch.algolia.com/apply/

Agreed. I already applied, but received a negative response. Will retry.
