Issue:
Zone: missing VerificationKey field 
Hello,

for enterprise customers deciding to create zones with the `partial` type (to use external DNS), the newly created `Zone` has an additional field `verification_key`. It wuold be great to add the field to the type to consume it elsewhere.

## Expected behavior

When calling `ListZones()` I would expect the enterprise zones to have `verficiation_key` field exported.

## Current behavior

The field is not present in `ZoneResponse.Zone`.

## Possible solution

add `VerificationKey` exported field in https://github.com/cloudflare/cloudflare-go/blob/c70f6a08eddbafee3dda58e9fab8302a1ea31d75/zone.go#L24 

## Context

This is useful in Terraform provider to read the activation key directly from the API and act on the external DNS provider.
