easy fix to https://x.com/kiritotwt1/status/1958452541718458513/photo/1
as it's generated of the types so should be accurate documentation. in
future it could be better done like what it may have been once upon a
time
(this doesn't fix the error, but it fixes the broken link)
* node:url implement domainToASCII and domainToUnicode
* fix arg checks
* remove unneeded use of WTF::Vector
* tidy
* throw a js error if icu fails
* add a ton more tests, fix ascii guard, upconvert latin1
* even more tests
* add a comment for this guard
* use ASSERT_NOT_REACHED() instead of raise(SIGABRT)
