Summary

Add a new enum constant RELEASE_20 to javax.lang.model.SourceVersion for the JDK 20 release and update the FooVisitor14 visitors to cover release 20 as well.

Problem

The SourceVersion enum needs an enum constant for each release being modeled.

Solution

Append the enum constant RELEASE_20 and update the visitor text and supported source version annotations to cover from RELEASE_14 to RELEASE_20.
