Recommend stack Elasticsearch Python client

[pquentin]

Relates #241. There's a Python Elasticsearch serverless client (https://github.com/elastic/elasticsearch-serverless-python), but we're planning to deprecate it.

_{run docs-build is much faster than run docs-build rebuild. A rebuild should only be needed in rare situations.}

LGTM!

@pquentin sorry I approved a little hastily, perhaps we should add an IMPORTANT note for users who happen to use the existing serverless client that we recommend using the classic client?

[pquentin]

We could, however there's near-zero usage of the serverless client today anyway. I was thinking more about adding a deprecation warning in the client itself.

OK that sounds reasonable! In that case should we update the title of this page to remove serverless mention?

Get started with the serverless Python client

Oops, definitely! Thanks, fixed it.
