issue #228 | Remove explicit dependency on Java plugin

https://community.sonarsource.com/t/new-release-aem-rules-1-5/61314/2

G Ann Campbell suggested that the `requirePlugins` metadata property
declaring a dependency on the Java plugin can be removed on the grounds
of Java analysis being an out-of-the-box feature.
