Feature Request: Support for multi-level TLDs like .asso.st, .fr.nf, .ze.cx, etc.

Hey!

Vercel does not seem to support domain names such as .asso.st, .fr.nf, .ze.cx, .infos.st, .biz.st, etc., which are provided by Azote.org. Vercel treats these domain names as subdomains, which prevents users from adding domain names with these extensions and results in an “already in use” error.

Would it be possible to add support for these domain names? All other platforms accept them, except Vercel, which is a real shame.

Thank you!

Be blessed and have a nice day :folded_hands:
