asciidoc3.org's blog mentions a complete revamp of their website. See https://asciidoc3.org/blog-news/2025/

Let's remove this CI target. There's no need to test a specific version of AsciiDoc 3 on every commit.

We could instead find a distro with some version of asciidoc3, but I don't think this is worth it.  Let's just remove it.
