x/website: update featured elasticsearch client

The Elasticsearch client currently featured at https://go.dev/, https://go.dev/solutions/webdev and https://go.dev/solutions/cloud is https://github.com/olivere/elastic, which has been deprecated (see the sidebar in the repo) in favor of the official client https://github.com/elastic/go-elasticsearch. As explained under "UPDATE 2022-07-13" in olivere/elastic#1533, olivere/elastic will not be updated for newer Elasticsearch versions.

This patch changes the featured Elasticsearch client from olivere/elastic to elastic/go-elasticsearch. It also updates the version of elastic/go-elasticsearch linked at the top of the webdev page. Lastly, it fixes typos in "A Elasticsearch client" -> "An Elasticsearch client" and "ElasticSearch" -> "Elasticsearch" (which is the correct spelling, per https://www.elastic.co/elasticsearch/).

Fixes golang/go#59028

 ### Go delivers speed, security, and developer-friendly tools for Web Applications
 
-Go is designed to enable developers to rapidly develop scalable and secure web applications. Go ships with an easy to use, secure and performant web server and includes it own web templating library. Go has excellent support for all of the latest technologies from [HTTP/2](https://pkg.go.dev/net/http), to databases like [MySQL](https://pkg.go.dev/mod/github.com/go-sql-driver/mysql), [MongoDB](https://pkg.go.dev/mod/go.mongodb.org/mongo-driver) and [ElasticSearch](https://pkg.go.dev/mod/github.com/elastic/go-elasticsearch/v7), to the latest encryption standards including [TLS 1.3](https://pkg.go.dev/crypto/tls). Go web applications run natively on [Google App Engine](https://cloud.google.com/appengine/) and [Google Cloud Run](https://cloud.google.com/run/) (for easy scaling) or on any environment, cloud, or operating system thanks to Go’s extreme portability.
