Link to Framework's docs about @Bean's autowireCandidate and defaultCandidate

[wilkinsona]

#22403 made some doc updates that refer to Framework's autowireCandidate and defaultCandidate @Bean attributes. There's now some information about these in Framework's reference documentation so we should link to https://docs.spring.io/spring-framework/reference/6.2-SNAPSHOT/core/beans/dependencies/factory-autowire.html#beans-factory-autowire-candidate from our docs.
