Spring RestTemplate initialization documentation in 6.0.x mentions Netty, yet no ClientHttpRequestFactory is present in the package.

Affects: 6.0.x

In the documentation of rest-clients.adoc it mentions that Netty is an option. Yet I only see this in the 6.1.x branch: https://github.com/spring-projects/spring-framework/commit/20dd66cd5a706b6a8960c64c08361d113390f557 of the org.springframework.http.client package. Also the Spring Boot v3.1.5 documentation does not mention Netty as an option for RestTemplate: rest-client.adoc.

This is related to the old Netty4ClientHttpRequest based on AsynHttpRequestFactory, deprecated in 5.0 and removed in 6.0. It seems this wasn't removed from the documentation. It has been there since 2018 with d007c25585517d59be4d72a5004f837a9e1205d3.
