Add happy announcement for the newborn

[verhasi]

This maven plugin helps to reduce the lib years of a product so it is an anti age tool. The final goal is to get the result 0 libyears what I mean newborn. Actually this happy moment remains silent. Event not the fact that it is 0 libyears is not printed at all.
I propose to provide a happy congratulation is something similar when a module reaches the newborn state.
May be I will create a PR for this feature if @mfoo thinks it is a good idea.

Heya! The library is heavily based on the MojoHaus Versions Maven Plugin, which doesn't have any kind of 'well done' message if you're on the latest versions. Do any of the other libyear plugins mentioned on https://libyear.com/ have a mention of congratulations if you hit zero? libyear-bundler doesn't.

I note that the oga-maven-plugin will print this though:

No problem detected. Good job! :-)

I think perhaps that my Maven builds are already noisy enough, more text when we hit zero years might not be super useful? What do you think?

As I tried out the plugin alone and not as part of the build, I was unsure whether everything was ok or something had gone wrong when there was no output at all. My use case was to focus on the anti-ageing the project and finishing was silent.
If executed as part of the build I believe 1 more line per module would not harm anyone.
As the maven is generally opinionated, this feature also could be implemented as printing congratulation as default but could be configured to switch off.

It could be an edge case but relates this discussion
