jakarta.enterprise.cdi-spec-doc is failing to build

[starksm64]

The main spec repo is failing to build under Java 11 as shown in the following error. The asciidoctor-maven plugin version is quite out of date. Just updating to the current 2.2.1 release fixes the problem and gets rid of the current illegal access warnings.
