Refs #36007 -- Added IDNA 2008 test case for URLValidator.

Test a domain that is valid under IDNA 2008 but not IDNA 2003. This
helps verify that the branch in URLValidator which calls punycode() is
not actually being used for IDNs. punycode() implements IDNA 2003, so
the domain would fail to validate if that branch were active for IDNs.
