Wildfly not providing JSF implementation?

Question

I´m just starting with JSF and Wildfly and I am facing a strange error. Following an excellent tutorial from BalusC (https://balusc.omnifaces.org/2020/04/jsf-23-tutorial-with-eclipse-maven.html) I arrived to the part where I have to run for first time the JSF project on Wildfly, but it fail, with an error which suggest Wildfly is not providing JSF implementation at all. Next is the stacktrace. Any help will very appreciate.

WildFly is currently downloadable as "Jakarta EE Full & Web Distribution" and "WildFly Preview EE 9 Distribution". The tutorial is written for "Jakarta EE Full & Web Distribution" only. The "WildFly Preview EE 9 Distribution" one uses jakarta.* package name instead of javax.* package.

The "Installing WildFly" section has been updated. Previously it said

WildFly is an open source Jakarta EE application server from Red Hat. You can download it from wildfly.org. Make sure you choose the “Java EE Full & Web Distribution" download and not, for example, the “Servlet-Only Distribution”.

It has now been updated to

WildFly is an open source Jakarta EE application server from Red Hat. You can download it from wildfly.org. Make sure you choose the “Jakarta EE Full & Web Distribution" download and not, for example, the “WildFly Preview EE 9 Distribution” or “Servlet-Only Distribution”.

Noted should be that "WildFly Preview EE 9 Distribution" can safely be used as long as you keep in mind to manually swap out javax.* for jakarta.* over all place in the tutorial.
