release mvnd version matching mvn embedded version

[hboutemy]

New feature, improvement proposal

IMHO, the fact that:

1. people need to learn that mvnd 1.x embeds Maven 3.x and mvnd 2.x embeds Maven 4.0
2. people need to learn that mvnd 1.0.4 embeds precisely mvn 3.9.14
   is part of why Maven Daemon does not really grow in the community as much as it should

It adds confusion

Would it be hard in the future to release mvnd 3.9.15 embedding mvn 3.9.15, mvnd 3.10.0 embedding mvn 3.10.0, mvnd 4.0.0-rc-6 embedding mvn 4.0.0-rc-6?

notice: IIUC, one dream future feature is to decouple mvnd from mvn, aka. letting one mvnd launch many different mvn versions (by downloading them instead of embedding them): pointer welcome if it exists

I imagine that at that time, we can have a new version 5, or 6 if Maven 5 is already out

+1 for aligning mvnd version numbers with those from Maven itself
