Fix acmesh-official#4836 (Switch to new Gandi LiveDNS API)

1. Updated LiveDNS API URL for the new API to allow Personal Access Tokens to work
2. Updated authorization header syntax to allow deprecated API Keys to work with the new API
3. Removed white space in JSON response parsing to match responses returned by the server
