I created this pull request to update the Ukrainian translation in uk-UA/translation.json as previously suggested by @SimonOriginal in an issue. Since the original suggestion was not submitted as a PR, I'm taking the initiative to submit the changes myself to contribute to the project. A huge thanks to @SimonOriginal for his dedication to the project and for taking the initiative to suggest the translation update in the first place!
