Rewrite metrics to support all new PMD metrics

[uhafner]

Add support for all new PMD metrics (see pmd/pmd@main...uhafner:pmd:7.7.0-patch-2). These new PMD metrics have been introduced in the bachelor theses of Maximilian Waidelich here at the University of Applied Sciences Munich, see #119.

The following metrics are now supported:

📐   Toplevel Metrics

🌀	Cyclomatic Complexity	355	1	8	1.73	1
🧠	Cognitive Complexity	172	0	11	0.84	0
📏	Lines of Code	3859	1	35	6.52	1
📝	Non Commenting Source Statements	1199	1	21	3.81	1
