revise mavenskeleton + try dependency check

[ebarboni]

Attempt to make the maven skeleton a bit more hierachical to match cluster and module name.

ant verify-libs-and-licenses is used to make skeleton on nbbuild/build/mavenpoms

mvn eu.maveniverse.maven.plugins:toolbox:0.15.17:dependency-versions can be launched on the folder root or in subfolder cluster to reduce scope.

i think this is the better approach. Initially I did the exact same and generated poms - I can't really remember why I ended up using the API via a script.

Feel free to remove the old workflow with the same commit to keep things clean.

nit: split line

          cd nbbuild/build/mavenpoms/
          mvn -B eu.maveniverse.maven.plugins:toolbox:0.15.17:libyear

btw, how about running libyear instead of dependency-versions?

difference: it will print less (won't show "up to date" lines) and it calculates age too, which can be useful for prioritization.

This is the most concice output I could come up with:

mvn -B\
 -Dorg.slf4j.simpleLogger.defaultLogLevel=warn\
 -Dorg.slf4j.simpleLogger.log.eu.maveniverse.maven=info\
 -DupToDate=true\
 eu.maveniverse.maven.plugins:0.15.17:toolbox:libyear

generates about 1200 lines.

I am not sure what the github limit is. Would be cool if we could post it there like the other action.

          echo "<pre>" >> $GITHUB_STEP_SUMMARY
          <command> | tee -a $GITHUB_STEP_SUMMARY
          echo "</pre>" >> $GITHUB_STEP_SUMMARY

oh nice. apparently github limits at 1MB - this will fit without problems.
