Subject: [PATCH] fix(i18n): drop repeated zh catalog keys and test that every
 key appears once (#2752)

Merges had added eleven zh.json keys a second time (Docker, Shell, the language
names, Add Service ({kind}), Others, Servers). JSON.parse silently keeps the last
copy, so nothing failed. The catalogs test now reads each catalog file and fails
on a key listed twice.
