refactor(prowler): Remove special test handling and fix linting issues
Parser Changes: - Removed unused 'test_file_name' variable to improve code cleanliness - Removed unused OS import, reduced dependencies - Cleaned up whitespace handling - Fixed docstring formatting issues Test File Changes: - Simplified if-else blocks to use ternary operators for better readability - Removed unused 'inactive_findings' variable - Updated comments to accurately reflect the actual checks being performed - Improved test case clarity by focusing on active findings validation
