Add support for Elasticsearch 16.x+

[jaffinito]

Describe the story, please be clear on scope of the story.

The current instrumentation for Elasticsearch only supports up to 15.x. In 16.x+ of the client, Elastic.Transport was updated to 0.5.2. This version changes the signature of the Request/RequestAsync APIs.

Old API: https://github.com/elastic/elastic-transport-net/blob/0.4.26/src/Elastic.Transport/ITransport.cs
New API: https://github.com/elastic/elastic-transport-net/blob/0.5.2/src/Elastic.Transport/ITransport.cs

This will require additional work due to the data we were using (http method, path, and request parameters) no longer being directly available as method parameters. I believe the data is still available, but we will need to look for it in other types.
