Fixes #25538 - Remove fuzzy translations for 'en' locale
Ruby code uses .mo files for the translations, but JS code uses a
generated JSON file containing the translation dictionary.
When generating the .mo file, fuzzy translations are ignored, but
when generating the json dictionary they are not.
Because en is the source locale, pulling translations from transifex
does not pull the English translation and thus the fuzzy translations
remain and are not removed when updating the translations.
This commit only removes the fuzzy translations, so on the next
translation update the json files will be generated correctly without
the wrong translations.
