Incorrect runtime complexity in Javadoc for clustering coefficient

[ameyabp]

If I am not mistaken, as per the current implementation of clustering coefficient, it should have a runtime complexity of O(V*max_degree^2) instead of O(V+max_degree^2).

https://jgrapht.org/javadoc/org.jgrapht.core/org/jgrapht/alg/scoring/ClusteringCoefficient.html

@AlexandruValeanu, could you please confirm and take appropriate action accordingly?

Thank you!
