Create pending_user_response.py (#13881)

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.
