Incorrect Croatian translations

[The generated Croatian locale](https://github.com/angular/angular.js/blob/3831e45a7d414cfa44297856689bd9added929f5/src/ngLocale/angular-locale_hr.js) isn't correct. Two last letters are misspelled in all months.

However, the sources (Google Closure) are correct https://github.com/angular/angular.js/blob/d3b1f502e3099d91042a1827a006ad112ea67d36/i18n/closure/datetimeSymbolsExt.js#L11328
