Link token interface was referenced in RandomNumberConsumerV2 contract and therefore also required by the deploy script. However, for VRF v2 to provide randomness, a consuming contract does not need to be aware of the Link token, as payment for the service is handled on subscription level.
I removed dependencies on Link contract, to make the code leaner and gas friendly 😎
