Documentation contains broken links to GitHub source files

Since Spring Boot 4.0.0, the links to the GitHub source files for the auto-configuration classes in the appendix are broken. They all result in a 404 on GitHub.

Example: the link on Spring Boot / Appendix / Auto-configuration Classes /
spring-boot-activemq to the source code of the ActiveMQAutoConfiguration class: https://github.com/spring-projects/spring-boot/tree/v4.0.0/spring-boot-project/spring-boot-activemq/src/main/java/org/springframework/boot/activemq/autoconfigure/ActiveMQAutoConfiguration.java

I found a few more broken links. I think it comes down to all links where {code-spring-boot}/spring-boot-project was used in the (AsciiDoc) source files.
