Bug#684260: zh_TW translations of "package", "repository" and "dependency" are mistranslated.

Well. As I previously reported that the mistranslation is kept using
for more than 20 years that almost becomes a proper noun.
The question is that should we make the change?

Some points:

* If the translation of the basis noun changed, there will be a long
transition period because all the documents are under transition, and
this may cause a big bang between Traditional Chinese dpkg existing
users.
* If not, it stays not an error by every existing users, but new users
may be confused by the translations.
