- Only run when changes are made on files inside 'sunshine' directory
- Prevents workflow from running again when this workflow pushes changes back into 'locale' directory
- Should be cleaner than using 'paths-ignore'
- Don't run if commits are all in 'locale' directory
- Allows pushing changes back into nightly from this workflow without triggering and endless loop
- Don't run job unless event is 'pull_request.merged'
