Update inaccurate section headers for backing up/restoring volumes (#13860)

* Change section headers for backing up/restoring volumes to use "volume" instead of "container"

The section headers "Backup a container" and "Restore container from backup" are used as headers for sections that are actually about backing up and restoring volumes.

* Minor style update
