Today we have an attribute in common called:

{{

}}

In the RH build of Quarkus downstream docs, when we link to the upstream Quarkus docs we use a variable that's set to the release version value that the docs need to map to. For example:

For instructions on how to install the Quarkus CLI, refer to the community-specific information at link:{url-quarkusio-guides}cli-tooling[Quarkus CLI].

Where:
:url-quarkusio-guides: https://quarkus.io/version/{ProductVersion}/guides/
:ProductVersion: 3.2

This generates the URL: https://quarkus.io/version/3.2/guides/cli-tooling

CHANGES NEEDED FOR UPSTREAM HARMONY:

1. Until the 3.2 doc tree is published by Guillaume, we cannot use the {ProductVersion}attribute in our {url-quarkusio-guides} value.
2. The upstream source also has an attribute called {quarkusio-guides} for the same purpose.
3. We must remove the trailing / from our attribute URL value as the upstream doc build adds a URL to processed links.
