LibWeb: Update Document.write spec steps

The spec changes seem to mostly be about introducing a TrustedHTML type which we do not yet support, so we have a couple of FIXMEs. TrustedTypes::InjectionSink is an attempt at matching the spec, but it's not entirely clear to me how it should work. I'm sure it'll get revisited once we start implementing trusted types.
