On https://spring.io/projects/spring-cloud-stream#learn there are two broken links:

• 4.1.3 links to https://docs.spring.io/spring-cloud-stream/docs/current/reference/html/, which shows the documentation for version 4.0.5.
• 4.1.4-SNAPSHOT links to https://docs.spring.io/spring-cloud-stream/docs/4.1.4-SNAPSHOT/reference/html/, which returns 404 Not Found.

It looks like the correct URL format is https://docs.spring.io/spring-cloud-stream/reference/${version}, because these work:

• 4.1.3: https://docs.spring.io/spring-cloud-stream/reference/4.1.3
• 4.1.4-SNAPSHOT: https://docs.spring.io/spring-cloud-stream/reference/4.1.4-SNAPSHOT
