Add support for .dev & .com.au & .au TLD

[huseyinkogo]

When monitoring DOMAIN_EXPIRATION with Gatus,

• Experiencing the following results
  [DOMAIN_EXPIRATION] (-9223372036854) > 720h (2592000000)

Requesting the following TLDS

• .dev
• .com.au
• .au
• .digital

I have also commented on the issue on Gatus repo (same issue)
TwiN/gatus#1159

I've been looking to find if there is whois server for .dev domains, and I didn't find one, but there is rdap server, which is replacement for whois can provide the registration information by doing GET request to https://pubapi.registry.google/rdap/domain/get.dev. Based on history of few of my .dev domains in my instance of gates, there was, but now it is gone.

$ curl -s https://pubapi.registry.google/rdap/domain/get.dev  | jq '{ ldhName: .ldhName,  expiration: (.events[]? | select(.eventAction=="expiration") | .eventDate) }'
{
  "ldhName": "get.dev",
  "expiration": "2025-10-10T19:35:58.234Z"
}

Not sure if rdap belongs here, or in a different repo.

FYI, RDAP support has been recently added to Gatus, with whois serving as fallback, so this may not be necessary for longer

thanks for that @TwiN, like currently .digital & .dev domains is working. But not au or .com.au
