Title: Consider consolidating `wp remote-backup initiate-download` and `wp remote-backup download`

The user's intention likely is just to have the file for local access.

Alternatively, these two could become `wp remote-site download` (with a loop mechanism), and `wp remote-backup download` would download the file for a specific backup ID.
