@cirx1e Apologies for my delayed review. Since the maintainer of the Traditional Chinese translation hasn't had much time recently, I'll be merging your review this time.

Although I'm not Taiwanese, can't be 100% certain about the accuracy of these translation reviews. Given your continuous help, I'll accept all of your translation suggestions, thank you!

I believe we are ready to go.

Sorry, I'm busy on preparing for college entrance affair, I can't review and update timely. We temporarily accept all you change and pull request if you wanna contribute and update this translation project until I can go back.

You can use this tool to automatically update timestamp, I use vs code with extension to work on this project.

Going to go ahead and pull this in for the next release. Thanks as ever yall
