remove nom.ad

[wdhdev]

Confirmed by the .ad registry:

Hi William.

We can confirm that the .ad TLD does no currently operate any functional public SLD. .nom.ad existed, in theory, some time ago, but is no longer offered and there is no currently existing domain under tht SLD nor any other. Only domains under the TLD .ad do exist and are available for registration.

Thanks for checking and for the good work tith PSL.

• Email was originally sent to info@domini.ad which is listed on the registry's site in the footer: https://www.domini.ad/contacte/ (Page URL can be verified through IANA's website: https://www.iana.org/domains/root/db/ad.html)
• I received a response from Amadeu Abril i Abril (CORE) <amadeu.abril@corenic.org>.
• You can also confirm yourself that the nom.ad TLD no longer is in use as you cannot find any active sites under a Google search or a subdomain scanner like https://subdomainfinder.c99.nl/ (I know, we cannot rely on these, however it is a good indication of usage)

I think we should be more thorough than quoting an email. The #2264 #2266 examples look more reasonable to me.

I have updated the PR template and will be more thorough in future. I can also forward you the email if you would like.

It would indeed be nice if we could get some more robust confirmation. @wdhdev @groundcat maybe you can ask the registrars to publish a list of subdomains they support on their site?

Merging this anyway because of I have a certain amount of trust that @wdhdev isn't making this up and I don't find it plausible that somebody else would have malicious replied to his mail.
