Describe the bug

When copying the sample code for VRFv2Consumer, the import for VRFCoordinatorV2Mock is incorrect, as presumably, the location of it has changed recently.

To Reproduce

1. Go to 'https://docs.chain.link/vrf/v2/subscription/examples/get-a-random-number#analyzing-the-contract'
2. Copy the code snippet into a file on your local machine.
3. Attempt to compile the smart contract.
4. Receive compiler error for the import.
