ext/intl: Fix argument positions in transliterator_transliterate() error message

[LamentXU123]

A missed case in #22044

<?php
  $tr = Transliterator::create('latin');

  try {
      transliterator_transliterate($tr, 'abc', 2, 1);
  } catch (ValueError $e) {
      echo $e->getMessage(), "\n";
  }

returns

transliterator_transliterate(): Argument #2 ($string) must be less than or equal to argument #3 ($end)

but I expect

transliterator_transliterate(): Argument #3 ($start) must be less than or equal to argument #4 ($end)

reproduce here

Now I think there won't be similar cases in the code base after this fix.
