Possibility to also check transitive dependencies?

Hi!
I really love the plugin, but it doesn't handle transitive dependencies.
Would it be possible to add an option to include these ?
This would help alot to find old outdated dependencies.

Hello, I think this can be added if the API of the Maven project exposes this. I believe it does from the top of my head.
Do keep in mind that this does result in many more requests to Maven central so it would take a while longer to fetch all the data, and be a lot more output!

I'm currently unable to free up time but happy to review PRs!
