Add missing parameters to the Interface submodule

[ce-torresorona]

TL;DR

Interface submodule attributes are out of date for version 6.31.0. I attempted doing a PR with the changes but no luck so I pass it on to the Google team.

https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_router_interface

Expected behavior

A router interface must have specified either ip_range or exactly one of vpn_tunnel, interconnect_attachment or subnetwork, or both

Observed behavior

Latest attributes not declared therefore fails
