Issue:
Add GET for /dcv_delegation/uuid
### Current cloudflare-go version

0.76.0

### Description

https://api.cloudflare.com/client/v4/zones/<zone_id>/dcv_delegation/uuid is not currently supported by the Go SDK. 

### Use cases

We need the ability to automate partial zone CNAME DCV delegation after zone creation in order to allow certificates to be auto-renewed.

### Potential cloudflare-go usage

```go
Simple Go SDK support for new endpoint.
```
