Rename ukrainian cities to proper spelling

[bgr11n]

Please, rename ukrainian cities to use up-to-date spelling, examples from wiki:

• Kyiv
• Zaporizhzhia
• Uzhhorod

Also maybe it make sense to have separately some id or slug field that should be persistent and name that may change?

@bgr11n Thank you for creating a PR, and I'm sorry for the late response.
I will check it later.

You're right, so I will improve it later, thank you!

[tkuchiki]

Could you please add it rather than rename it for backward compatibility?

[bgr11n]

@tkuchiki But in that case there will be duplicates?

[tkuchiki]

Yes. In that case, do you have any concerns?

[bgr11n]

@tkuchiki No, just wanted to clarify that it is expected.

LGTM, thank you!
