[Feature] Translating MQTTX UI into Traditional Chinese

[CasperHK]

Motivation

The current MQTT X UI and documentation are only available in English, Simplified Chinese, Japanese... This creates a barrier for users who are more comfortable with Traditional Chinese (e.g., developers and operators in Taiwan, Hong Kong, and other traditional Chinese users). Switching between the application and a translation tool slows down workflow, reduces usability, and may discourage adoption in markets where Traditional Chinese is the primary language.

Goal

1. Language resources – Create zh‑Hant translation files that contains translations for all UI strings, tooltips, error messages, and dialog texts.

2. Documentation – Provide a Traditional Chinese version of the README, user guide, and FAQ under docs/zh‑Hant/. Link these from the main README.

Hi @CasperHK, thanks for the feature request! We'll consider this for future releases. We'd welcome a PR with the translation files - you can directly submit the zh-Hant translation files, and we can handle the remaining implementation. Thanks!
