🛠️ Automating Configlet Sync

This PR introduces a workflow that automates configlet sync for test (only an issue is raised), docs, metadata, and filepaths.

⏱️ The workflow is currently scheduled to run on the 15th of every month via cron.
Let me know if you'd prefer a different schedule (e.g., weekly, the 1st of each month, etc.).

This setup is already being used across multiple tracks!.
