Add backward-compatible add_note helper for Python <3.11

[Copilot]

Replace exc.add_note(repro_snippet) with add_note helper function

Summary

This PR implements a backward-compatible add_note helper function to replace direct calls to exc.add_note(), which is only available in Python 3.11+. The helper function provides compatibility for older Python versions while maintaining the same functionality.

Changes Completed

• Merge upstream/master branch into current branch
• Add add_note helper function to pytest_helpers.py with backward compatibility
• Export add_note in pytest_helpers.py all list
• Replace all 62 occurrences of exc.add_note(repro_snippet) with ph.add_note(exc, repro_snippet)
  • test_array_object.py (1 occurrence)
  • test_creation_functions.py (14 occurrences)
  • test_data_type_functions.py (14 occurrences)
  • test_manipulation_functions.py (12 occurrences)
  • test_searching_functions.py (6 occurrences)
  • test_set_functions.py (4 occurrences)
  • test_sorting_functions.py (2 occurrences)
  • test_statistical_functions.py (9 occurrences)
• Fix docstring formatting per code review feedback
• Add reference link to Hypothesis issue for context
• Add Python 3.10 to test matrix in GitHub workflow

Testing

• ✅ Verified add_note function works correctly on both Python 3.11+ and older versions
• ✅ Ran comprehensive test suite - all tests pass
• ✅ Code review completed - all feedback addressed
• ✅ Security scan with CodeQL - no vulnerabilities found

Original prompt

Send a pull request to this repository, replacing exc.add_note(repro_snippet) by add_note(repro_snippet), where add_note is imported from pytest_helpers.py, and is implemented as follows:

def add_note(exc, note):
    try:
        exc.add_note(note)
    except AttributeError:
        if not hasattr(exc, "__notes__"):
            try:
                exc.__notes__ = []
            except AttributeError:
                return  # give up, might be e.g. a frozen dataclass
        exc.__notes__.append(note)
