chore(i18n): use english as the base language for i18n (#22)

* chore(i18n): use english as the base language for i18n

rewrite all of the locale files to use english as base for translation

* fix(i18n): update rest of the scripts that rely on the chinese-base i18n translation

* chore(i18n): change some of the base strings to be more correct

* chore(i18n): sync locale on dev

* chore(format): run black on dev
