Refactor cherry_pick_v2.py to use Any type for PullRequest references

This commit updates the `cherry_pick_v2.py` script to replace specific type hints for PullRequest with the more generic Any type. This change enhances flexibility in handling PullRequest objects, accommodating potential variations in the GitHub API.

Key changes:
- Updated type hints for `pull_requests` and related functions to use `Any` instead of the specific `PullRequest` type.
- Adjusted function signatures to reflect the new type annotations, improving code maintainability and compatibility with future API changes.
