Update mobileconfig.j2 (#1197)

Adds "Algo VPN" to the organization in the "Profiles" menu of "General Settings". (The type still shows up as "Unknown" in the "VPN" menu, because that seems to be governed by the "VPNSubType" string, which must be empty according to the [developer reference](https://developer.apple.com/enterprise/documentation/Configuration-Profile-Reference.pdf) Maybe this can help clear the way for #1101.
