Network prefix format Incorrect in yaml routes example

[jimmyt86]

Since v3.4.3 it's no longer possible to pass a network prefix length in the netmask field of network::route_hash. I have corrected the documentation example. This was the only occurrence across the module. Given the variable is called netmask, it was probably never intended to accept network prefixes

Looks like this issue can be closed, then.
