Create run-configlet-sync.yml (#2074)

### 🛠️ Automating Configlet Sync

This PR introduces a workflow that automates `configlet sync` for test
(only an issue is raised), docs, metadata, and filepaths. There are two
jobs in the main workflow; we can skip either one of them. Let me know
how you'd like to set it up!

⏱️ 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!.
