[New Feature]: Workflow for closing old PRs

[Asymtode712]

🎮 feature Request

Over time, open pull requests (PRs) can accumulate in a repository, cluttering the interface and making it difficult to focus on active development tasks. Additionally, outdated or abandoned PRs may no longer serve their intended purpose and should be closed to maintain repository cleanliness.

Implement a workflow that automatically closes old PRs based on predefined criteria, such as their last update timestamp. By regularly closing PRs that have not been updated within a certain timeframe, the repository can stay organized, and contributors can focus on active and relevant PRs.

Point down the features

This feature aims to automate the management of open PRs in a repository, ensuring that outdated or abandoned PRs are closed in a timely manner. By doing so, it helps maintain repository hygiene, improves workflow efficiency, and provides a better experience for both maintainers and contributors.
