correct russian ordinal of 3

add case missed in #211

@hazzik there is more uncovered cases, like for 21.000, 230.000.000 or 2.000.000.000
Actually it's not a big deal, cause how often do you get a two-billionth request :) But for completeness we should tackle those case also.
```
        [InlineData(21000, "двадцатиоднатысячьный")]
        [InlineData(230000000, "двухсоттридцатимиллионный")]
        [InlineData(2000000000, "двухмиллиардный")]
```
