feat: lint fix

Changes
-------
 - Bump frontend-platform to bring `intl-imports.js` script
 - Move all i18n imports into `src/i18n/index.js` so `intl-imports.js` can
   override it with latest translations
 - Add `atlas` into `make pull_translations` when `OPENEDX_ATLAS_PULL`
   environment variable is set.
 - Refactored i18n utils into own file to avoid overwriting them by
   atlas
