Add documentation in Ukrainian

[Andygol]

Description

I am pleased to present the translation of Istio's documentation into Ukrainian 🇺🇦. I hope this contribution will be reviewed and incorporated into the documentation.

The translation contains all the documentation except for the Reference/Configuration and Reference/Commands sections, which I hope will be added later.

Everything looks good except for one drawback. I couldn't get the desired result locally with the FAQ page in Ukrainian, while the English and Chinese versions work as expected. I have an issue (locally), when I click on a question, no action is taken, the answer section is not displayed.

If I missed something, please correct me and let me know what it was. 🙏
