Improve check_exception_against_list matching logic using regex

Changes:
   - `match_exception_with_traceback` uses regular expressions for more
     flexible matching of file paths and line numbers. This allows for
     partial matches and more complex patterns.

   - Improve `check_exception_against_list` by delegating to
     `match_exception_with_traceback` for checking tracebacks against
     exception list entries.

   - `load_exception_list`: Remains largely unchanged, as it correctly
     parses the file and line number from each exception entry. However,
     we ensure the set consists of regex patterns to match against
     tracebacks.
