SpringBoot Investigate oddities in the configuration properties changelog

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0.0-M1-Configuration-Changelog

There are some properties without descriptions and also some that are reported as having been removed when they have not been.

Comment From: snicoll

The HTTP client properties missed some of the documentation due to org.springframework.boot.http.client.autoconfigure.AbstractHttpRequestFactoryProperties not being flagged a @ConfigurationPropertiesSource.
