Crawl overview failure

Describe the bug

Running Crawljax 5.0 after building a fat jar (with all dependencies) gives this error:

Exception in thread "main" java.lang.NoSuchMethodError: 'com.fasterxml.jackson.annotation.JsonIgnoreProperties$Value com.fasterxml.jackson.databind.AnnotationIntrospector.findPropertyIgnoralByName(com.fasterxml.jackson.databind.cfg.MapperConfig, com.fasterxml.jackson.databind.introspect.Annotated)'

I tried it again after the fix, and the fat jar built from a project with Crawljax dependency (https://github.com/konveyor/tackle-test-generator-core/tree/main/tackle-test-generator-ui) still fails with the same error:

The root cause seems to be the jackson dependency introduced by webdriver-manager in the core module. Current workaround is to use dependencyManagement for jackson inside the pom file that is building fat jar.

   <dependencyManagement>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>
                <version>2.14.2</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

The problem does not manifest in the crawljax-examples module because the crawljax-parent-pom includes the dependencyManagement for jackson. However, any external project that is trying to build a fat jar will have to include this as well.
