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. - package.json and package-lock.json are copied from https://github.com/openedx/frontend-app-ora-grading/pull/176 - updated snapshots and updated tests in sync with `frontend-platform` - require package-lock.json version 3: same as https://github.com/openedx/frontend-app-ora-grading/pull/176 Refs: [FC-0012 project](https://openedx.atlassian.net/l/cp/XGS0iCcQ) implementing Translation Infrastructure OEP-58.
