[DOCS] Add data stream lifecycle links

[lcawl]

This PR adds @ext_doc_id links to https://www.elastic.co/docs/manage-data/lifecycle/data-stream from APIs like get data stream lifecycles, since the Data streams group currently only points to an overview of data streams.

This is a demo as part of a discussion with @stefnestor about how to add these types of links in general. The OpenAPI output is generated via make generate and make transform-to-openapi commands.
