Implement prioritized job pattern checking

This commit introduces a prioritized, cascading job pattern checking
feature to the `print_workflow_run_errors.py` script.

Key changes:
- The `--job-pattern` argument now uses `action='append'`, allowing users
  to specify multiple patterns. These are checked in the order provided.
- If no `--job-pattern` is specified by the user, a default prioritized
  sequence is used: `['^build.*', '^test.*', '.*']`.
- The script iterates through the determined list of patterns:
    - For the first pattern that matches jobs AND has failures among those
      matched jobs, the script processes and displays logs for those
      failures.
    - It then stops checking subsequent patterns.
- If a pattern results in no matching jobs, or if all matching jobs
  succeeded, the script moves to the next pattern in the sequence.
- Informative messages are printed to stderr indicating which pattern is
  being checked, the outcome for that pattern, and if subsequent
  patterns are skipped.
- The main log processing loop has been refactored into a helper function
  `_process_and_display_logs_for_failed_jobs` for better organization.
- Handles invalid regular expressions within the pattern list by warning
  the user and skipping the invalid pattern.
