Bump ManagerNetworkProtocol to fix error

The RedfishServiceValidator throws the following error:
"ERROR - Verifying property that does not belong to this
version: ManagerNetworkProtocol.v1_2_0.ManagerNetworkProtocol:NTP"

NTP was added in version 1_2_0. Bumped to latest, 1_4_0.

Tested: Ran RedfishServiceValidator and no longer observe the
        error.
