**Problem:** In https://github.com/elastic/docs/pull/2752, we updated the URL prefix (`welcome-to-elastic`) and name for the "Welcome to Elastic Docs" docs. However, we still have some stray links that use the old `/welcome-to-elastic` URL prefix
**Solution:** Updates several outdated links.
- Adds the TOC to the Elasticsearch docs landing page. Removes the right sidebar from the landing page.
- Removes the "View all Elastic docs" link from the bottom of the landing page
