Enhance check_id extraction logic in ProwlerParser

- Simplifies extraction of check_id from finding_info for various formats
- Adds support for retrieving check_id from metadata.event_code in official Prowler OCSF JSON format
- Ensures robust handling of check_id retrieval across different data structures
