Add Traditional Chinese (zh_TW) translation

[jasoncheng7115]

I have added the zh_TW.json translation file for Traditional Chinese,
but it does not appear as an option in the language selection menu.

@jasoncheng7115 Thanks for contributing this. There's a couple of things that need to be done:

• You need to request a Jira account and create a Jira issue for this, and tag both the PR and the commit messages with the GUACAMOLE-XXXX issue.
• Please make sure not to include anything that you're not translating in the translation file.

See: https://guacamole.apache.org/open-source/

As far as why the translation is not loading, I'd say the first thing to check is clearing your browser cache and reloading the page to see if that gets the language to load. Other than that, maybe increase the log level of the web application and see if there are any messages about the new language file in there?

Please do not include these values in the translation - they will be pulled automatically from the English translation.

Thank you for your detailed explanation. I will review and learn more about the Guacamole contribution process and then make the necessary corrections.
