Signed-off-by: GitHub <noreply@github.com>

* Refactor C# Cognitive Complexity Analyzer and Update Tests

- Improved function name retrieval logic in CSharpCognitiveComplexityAnalyzer to handle special function types more efficiently.
- Enhanced visit method to skip nested function declarations, preventing double-counting in complexity calculations.
- Updated unit tests for complexity analyzer factory and C# language analysis to use 'suite' and 'test' instead of 'describe' and 'it'.
- Added comprehensive tests for various C# constructs, including control flow statements, exception handling, and logical operators.
- Introduced debug script for analyzing complexity calculations in C# functions.
- Created a test suite index file to streamline test execution and loading.
