fix: download-builds improvements (#23104)

## **Description**

Two improvements to `yarn download-builds`

1. No longer uses `sudo`
2. More graceful exit if no builds can be downloaded

## **Manual testing steps**

1. Run `yarn download-builds` in a place that would have required `sudo` before
2. Make sure no password is required
