cmd/devp2p: require dns:read, dns:edit permissions for cloudflare deploy

[praetoriansentry]

This PR adds the dns:read and dns:edit permissions to the required set of permissions checked before deploying an ENR tree to Cloudflare. These permissions are necessary for a successful publish.

Background:
The current logic for devp2p dns to-cloudflare checks for zone:edit and zone:read permissions. However, when running the command with only these two permissions, the following error occurs:

wrong permissions on zone REMOVED-ZONE: map[#zone:edit:false #zone:read:true]

Adding zone:read and zone:edit to the API token led to a different error:

INFO [08-19|14:06:16.782] Retrieving existing TXT records on pos-nodes.hardfork.dev
Authentication error (10000)

This suggested that additional permissions were required. I added dns:read, but encountered another error:

INFO [08-19|14:11:42.342] Retrieving existing TXT records on pos-nodes.hardfork.dev
INFO [08-19|14:11:42.851] Updating DNS entries
failed to publish REMOVED.pos-nodes.hardfork.dev: Authentication error (10000)

Finally, after adding both dns:read and dns:edit permissions, the command executed successfully with the following output:

With this PR, the required permissions for deploying an ENR tree to Cloudflare now include zone:read, zone:edit, dns:read, and dns:edit. The initial check now includes all of the necessary permissions and indicates in the error message which permissions are missing:

INFO [08-19|14:17:20.339] Checking Permissions on zone REMOVED-ZONE
wrong permissions on zone REMOVED-ZONE: map[#dns_records:edit:false #dns_records:read:false #zone:edit:false #zone:read:true]
