feat: enable maven enforce-plugin-versions rule

[taefi]

To prevent having old plugins accidentally resolved by maven during the build. For example, after renaming groupIds to com.vaadin there was still hilla-maven-plugin from com.vaadin.hilla being used during the builds, and maven was resolving the last existing version of the plugin instead of only one version in use for the whole project.

NOTE: Enabling enforce-plugin-versions is not enough.
