Subject: [PATCH] TOML checker: permit long TLDs

Longest [top-level domain in use today](https://data.iana.org/TLD/tlds-alpha-by-domain.txt) is 24 characters long (`XN--VERMGENSBERATUNG-PWB`) so I extended the TLD portion of the field validation to that length, with hyphens allowed in the middle but not the beginning or end of the TLD.
