Update dependencies

* Declared directly required versions in the dependencies section.
    * Added script-security as groovy-script utilizes it.
    * Removed workflow-step-api as groovy-script itself doesn't use it even in tests.
* Reordered dependencies. Mandatory dependencies, optional dependencies and test dependencies.
* Use the least versions.
    * workflow-job-2.26 is required to test JENKINS-54128.
* Removed properties to specify dependency versions.
    * No longer necessary as they are used to synchronize versions for artifacts without classifier and with classifier=tests.
