What would you like to be added:

I propose adding a GitHub Action that automates the process of syncing team members with a members.yaml file. This feature would enhance our workflow by ensuring that team membership is regularly updated without manual intervention.

Currently, there is an available action called github-team-sync. However, developing our own tailored action would be beneficial to better meet our specific needs and requirements.

Why is this needed:
Automating the membership syncing process will save time, reduce the potential for errors, and ensure that our team settings remain current. This enhancement can lead to a more efficient workflow and improved member management.
