feat: add Ukrainian translations and locale support

[danulqua]

Added the Ukrainian uk_UA translations.

I'd recommend keeping these sorted according to their ASCII ordering.

[pluiedev]

Actually the order does matter. See the doc comment above

I'm not sure why I got tagged for review (I know pretty much nothing about Ukrainian) but at a glance nothing seems particularly wrong. The strings may be a bit too long, though — have you tested your translations within Ghostty and see how much space the strings take up? (It's especially crucial for context menus where one ideally shouldn't have the menu covering half of the screen.)

[danulqua]

@pluiedev I'm on macOS, and I heard that translations are not yet available here, so I can't test it. However, I was referring to other terminal apps and to the Ukrainian language in macOS in general - it's okay that some strings may be longer than in English. I also tried to keep them the same length in cases where multiline strings are being used as you can see.

Do you accept the responsibility to be on the uk_UA localization team and get pinged for future string changes?

[gordonbondon]

I've been working on Ukrainian translation as well. But @danulqua beat me to it : )

If you need more than one person to maintain Ukrainian translation I would be glad to help.

@danulqua Ukrainian does not have capitalization like here: "Відкрити Конфігурацію".
That's probably ok, bit it's not consistent with "Перезавантажено конфігурацію" (which I would also change to "Конфігурацію перезавантажено")

[danulqua]

@mitchellh Yes, I would be happy to contribute!

@varyform

Ukrainian does not have capitalization like here: "Відкрити Конфігурацію".

Translations preserve the capitalization from the original text, as you can see; nothing was changed on my end in this context.

"Перезавантажено конфігурацію" (which I would also change to "Конфігурацію перезавантажено").

I'll update this one, thanks.

[pluiedev]

Just FYI, GNOME Console doesn't do title case either and we should follow what it does

[danulqua]

@pluiedev I checked the macOS Terminal app in Ukrainian, and indeed, it also isn't using title case. I just thought that we should preserve the case from the original text. Now I will keep that in mind.

I pushed a fix that removes title casing.

[mitchellh]

Thanks for addressing feedback. Updated the code owners file and fixed some merge issues.

I found some blank translations
