Document typical spring.application.name use

[wleese]

The documentation on https://docs.spring.io/spring-boot/appendix/application-properties/index.html#application-properties.core.spring.application.group is non-existent. It would be a lot more useful if some kind of explanation / context is provided as to how this property will be used by Spring Boot.

It isn't non-existent. Searching for spring.application.group produces the following results:

• https://docs.spring.io/spring-boot/reference/features/logging.html#features.logging.log-format
• https://docs.spring.io/spring-boot/reference/features/logging.html#features.logging.log4j2-extensions.environment-properties-lookup

There's also some information about the property in the release notes for 3.4.

It would be nice if the properties overview would provide more of an indication of what the property can be used for without having to search for it elsewhere.
