Spring Cloud Release Docs Needs To Be Updated With Correct Versions When Marked Ready

[ryanjbaxter]

When marking Spring Cloud Release "ready" we need to not only replace the versions in the POM but also update the versions in the docs

https://github.com/spring-cloud/spring-cloud-release/blob/main/docs/modules/ROOT/pages/_spring-cloud-links.adoc
https://github.com/spring-cloud/spring-cloud-release/blob/main/docs/modules/ROOT/pages/index.adoc

Maybe we can run this class without the need to pull dependencies for other cloud/boot projects?
