The ArtifactVersion leaks into public API

[Larusso]

Description

The following dependency declaration makes the 'org.apache.maven:maven-artifact' an implemenation only depdency.

atlas-unity/build.gradle

Line 46 in 55a479b

implementation 'org.apache.maven:maven-artifact:3.8.2'

But projects pulling this plugin also need to pull this dependency into the classpath when extending or writing custom tasks.
We need to redefine this dependency as API or update its internal usage so it won't leak.
