There are section titles that appear in a great number of Wikipedia articles: "Biography", "Early life", "Bibliography", "External links", "References", "History", "Legacy", etc.
When machine translation is not available (and even if it is) these section titles can be auto-translated by the CX software. The translations can be stored in the usual i18n JSON files.
This should save translator a few seconds on each of these sections.
