Create pending_user_response.py

Python script for Workflow automation for pending_user_response.yml based on the following:

- If an issue or PR has 'needs-user-input' label, and it has been 30 days since the last comment, comment and tag the user asking them to take a look.
- And 30 days after this comment from the workflow, if no response, close the issue with a comment stating the user did not respond and they can re-open if needed.
- If the user responds, remove the 'needs-user-input' label.
