Add GitHub Actions for Automated Labeling and Triage of PRs and Issues

[krapie]

Description:

I propose the addition of GitHub Actions to automatically triage, label, and assign pull requests (PRs) and issues across all repositories in the yorkie-team organization. This functionality is essential for effectively tracking all issues and PRs and will significantly enhance our workflow.

Additionally, I recommend implementing a feature that automatically assigns labels when team members create PRs or issues. This capability will be especially useful during the Open Source Contribution Academy (OSSCA), where mentees will be associated with OSSCA team members. The automated labeling will allow us to monitor and gather metrics related to OSSCA activities more effectively.

Why:

With the increase in contributions and activities across the organization, the automation of labeling and triaging will streamline the management process. It will improve visibility into ongoing contributions and ensure that we can effectively track the progress and engagement during OSSCA, ultimately fostering a more organized and efficient open-source contribution environment.
