Update javaparser to 3.20.2 and improve check in VariableAction.DeclarationType

The latest release of JavaParser includes a bugfix for `ResolvedValueDeclaration#isVariable()` (see issue [3159](https://github.com/javaparser/javaparser/issues/3159)). The check in `VariableAction.DeclarationType#valueOf` can now be updated.
