Include Wildscribe documentation with the default WildFly doumentation

Currently all the model, Wildscribe, documentation is hosted at https://wildscribe.github.io/. With the quicker releases of WildFly this is becoming rather large as a single place to store this documentation. A solution to this is to include the model documentation in the WildFly documentations hosted at https://docs.wildfly.org. Each version, from WildFly 19 on, will have a https://docs.wildfly.org/$VERSION/wildscribe directory which will host the model documentation.
